PERIOD CHANGES OF RR LYRAE STARS I. AT AND, SU DRA, RR LEO, TT LYN AND AR PER ABSTRACT Photographic and photoelectric observations obtained at Konkoly Observatory during the past 45 years are presented. Using all available observations the O-C diagrams of AT And, SU Dra, RR Leo, TT Lyn and AR Per are constructed. Period jumps are characteristic of AT And and TT Lyn. In the period of AT And two jumps occurred: +710x10^-8 days in 1956 and -545x10^-5 days in 1962 (Figure 2). The period of TT Lyn is constant, but a jump of 8x10^-5 days might have taken place in 1958 (Figure 10). The O-C diagram of SU Dra consists of waves of small amplitude, the photoelectric maxima from 1955 were able to be fitted by a straight line (Figure 5). The period of AR Per shows a constant increase with time at a rate of 1.01x10^-8 days/year (Figure 13). The period of RR Leo also shows an increase at a rate of 15.849x10^-8 days/year during the past 70 years. A more rigorous period analysis showed that cyclic variations with an amplitude of 0.006-0.007 days and with cycle length of 25000 epoch numbers were superimposed on the positive parabolic O-C diagram (Figures 7 and 8). INTRODUCTION Forty-five years ago L. Detre commenced to observe RR Lyrae stars at the Konkoly Observatory with the aim of investigating their possible multiple periodicity and secular period changes. In the thirties it was firmly believed that the evolutionary changes in the stars' constitution were reflected in the period changes. We now know that the question of period changes is more complex. The well-observed field RR Lyrae stars provide a good opportunity for us to investigate not only the rough structure but also the delicate features of their O-C diagrams as well as the minute changes in their periods. In this way it is hoped, that we will be able to elucidate the confused problem of period changes of RR Lyrae stars. Under the stimulation and inspiration of the late director of the Konkoly Observatory, L. Detre, we have buckled down to the task of processing the photographic and photoelectric data obtained at our observatory during the past 45 years and to collecting all the available moments of maximum of the RR Lyrae stars in order to construct precise and detailed O-C diagrams. In this paper we present the results on the RR Lyr type stars AT And, SU Dra, RR Leo, TT Lyn and AR Per. In subsequent papers we plan to publish our results on further RR Lyrae variables. OBSERVATIONS Since 1933 through the years some thousands of photographic and about 150000 photoelectric observations have been collected for field RR Lyrae variables at the Konkoly Observatory. The photographic observations were made with a 16 cm astrograph mostly using Kodak Eastman 40 and Guilleminot Superfulgur plates. The typical exposure times were 2-5 minutes. Photographic observations ceased in 1957. The photoelectric observations were first carried out using the 60 cm Newton telescope at Budapest in 1952. Initially the observations were made without filters but since 1954, conventional filters of the UBV system have been used. The mirror of the telescope was first aluminized in 1963. The following multipliers were used: an RCA 931 A with Schott filters BG 12 in B and GG 11 in V; from 1954 an RCA 1P21 with Schott filters UG 1 in U, BG 12 + GG 13 in B and GG 11 in V; and after the aluminization of the mirror in 1963 an EMI 9052 B with the same filters as in the previous years. Since 1972 photoelectric observations were also made close to the international UBV system with the new 50 cm telescope at Konkoly Observatory's mountain station. At this location we used an integrating photometer equipped with an unrefrigerated EMI 9058 QB photomultiplier and the following Schott filters: UG 2 in U, BG 12 + GG 13 in B and GG 11 in V. The photoelectric observations have been transformed into the UBV system in the traditional way (see e.g. Hardie, 1962). The journal of the observations of AT And, SU Dra, RR Leo, TT Lyn and AR Per is given below. Table 1 star year kind number star year kind number of obs. of obs. of obs. of obs.

Asterisks indicate that the observations were carried out without filters and are not, of course, converted into the UBV system. AT ANDROMEDAE AT And = 178.1935 And was discovered by Morgenroth (1935). Lange (1935) classified the star as an RR Lyrae variable and gave the preliminary ephemeris: J.D. max. hel. = 2428022.37 + 0.628dxE During the past 40 years a number of visual and photographic observations were carried out on this star. Parenago (1940) investigated AT And on 431 photographic plates of the Moscow Sternberg Institute and determined the following new elements: J.D. max. hel. = 2429146.347 + 0.6169129dxE The amplitude of the light variation turned out to be fairly small, only 0.53m pg. Other visual and photographic maxima were derived from the observations of Kippenhahn (1953), Alania (1956), Lange (1959, 1968), Tchumak (1965), Daube (1969), Romano and Perissinotto (1969) and Kanishcheva and Lange (1971). Tsessevich (1966) examined the old Harvard plates and gave a very important time of maximum for the year 1906. Tchumak (1965), using both Parenago's and Tsessevich's observations, stated that this star had a strong Blazhko effect. According to him the period of the secondary variation of the light curve was P_B = 82.75d and during this cycle the O-C oscillation of the maxima was 1.5 hours = 0.06d = 0.10p. Lange (1968) and Olah (1975) questioned Tchumak's results. Here we publish all the photoelectric observations obtained at the Konkoly observatory in 1974, 1975 and 1977 (Table 8). These observations (see Figure 1) clearly and unambiguously show that AT And has a stable light curve and does not possess Blazhko effect. Other photoelectric observations (Fitch et al. 1966, Sturch 1966, Epstein 1969) also confirm the stable character of its light curve.
Figure 1: B and V light curves of AT And
The comparison star used for the photoelectric observations at Konkoly
Observatory was BD +42deg 4739. Its magnitude and colour were adopted from
Sturch (1966): V = 9.465 and B-V = 0.372.

All the published maxima are given in Table 2. For each year we determined
a mean value of O-C's. The O-C diagram (Figure 2) was constructed by using
these mean values with the elements:
J.D. max. hel. = 2442343.4205 + 0.61691475dxE
Figure 2: O-C diagram of AT And
Because of the abnormally wide scatter of Tchumak's observations, they
were omitted. We also did not take into account Alania's maximum in
constructing the O-C diagram.
The O-C diagram can be approximated by broken lines. The periods are:
interval period
- 2436000 0.61691310
2436000 - 2438000 0.61692020
2438000 - 0.61691475
The period jumps were +710x10^-8 days and -545x10^-8 days.
SU DRACONIS
This bright RR Lyrae type variable was discovered by Miss Leavitt from plates
of the Harvard Map of the Sky; its variability was announced by Pickering
(1907a). The first investigators of SU Dra = BD +68deg 652 (9.5) = HD 100971
(A2) = 43.1907 = HV 2900 = AG Chri 1788 (9.4) were Enebo (1907, 1911), Seares
(1908), Sperra (1909) and Ginori (1912). Their visual observations yielded a
fairly good period of the star. Martin and Plummer (1913) found strange
fluctuations superimposed on the light curve. Since Martin and Plummer's
observations a great number of accurate photographic and photoelectric
observations have been collected but this unusual phenomenon has never
again been seen. Certainly these fluctuations resulted from the fairly
large observational errors of Martin and Plummer.
The period change of SU Dra can easily be followed. The star has been
observed almost continuously over the years. Floria (1931, 1933), Lange
(1938, 1960), Soloviev (1934a,b, 1936a,b), Ahnert (1960b), Sacharov
(1964) and Braune et al. (1970,1972,1973) carried out visual observations,
Robinson (1933), Jordan (1929), Kepinski and Kowalczewski (1934), Dziewulski
(1938,1951), Opalski (1938), Alania (1956), Koshuba (1961) and Harding and
Penston (1966) photographic observations. Payne-Gaposchkin (1954), using the
old Harvard plates, gave the first known time of maximum.
Tsessevich (1966) rediscussed a few observations and gave new maxima.
We have not included Jost's data (Jost, 1933) in our discussion because of
the large observational errors. The most accurate moments of maximum were
obviously obtained from photoelectric measurements (see Geyer (1961), Spinrad
(1961) and Fitch et al. (1966)).
In the years 1939, 1946, 1952 and 1954 the star was photographically
observed at Konkoly Observatory. The measurements are given in Table 10.
We used the following comparison stars (see Figure 3) :
star m_pg
A 9.11
B 9.96
C 10.24
D 11.10
Figure 3
The first photoelectric observations were made at our observatory without
filter in 1955. These observations of course cannot be transformed into the
international UBV system. Later on, our photoelectric observations were
obtained in a system close to the international one. Our data are given in
Table 9 and in Figure 4. As a comparison star we used BD +68deg 655. A tie-in
observation yielded for this star: V = 9.26, B-V = 1.05, U-B = 0.98.
The photoelectric observations clearly show that SU Dra has a stable,
repetitive light curve.

Remarks: 1 omitted, 2 rediscussed by Floria (1933), 3 rediscussed by Tsessevich (1966)
The times of maximum are collected in Table 3. The residuals were
calculated by the elements:
J.D. max. hel. = 2420605.7620 + 0.66041890dxE
From the O-C values yearly means were formed. These are plotted against
epoch numbers in Figure 5. The waves in the O-C diagram seem to be real.
Since 1955 the O-C values using only the photoelectric observations can
be approximated by a straight line, i.e. with the period 0.66042001d.

RR LEONIS
The variability of this star RR Leo = BD +24deg 2183 (9.4)= 170.1907 = HV
3015 was discovered by Leavitt (Pickering, 1907) on Harvard photographs.
Luizet later determined the period. At first he found it to be 4.74867
days (Luizet, 1909) but later determined it as only 0.452368 days
(Luizet, 1911a). Luizet (1911b) gave a long list of maxima from his
visual observations. We were of the view that Luizet's observations
should be rediscussed and that normal maxima be determined using his
data.
Martin and Plummer (1921) derived the light curve of this star and found
secondary oscillations which have never been present in any of the light
curves ever observed. The time of maximum was redetermined using Martin
and Plummer's data but it still remained very uncertain because they
used exposition times of 34-60 minutes.
Jordan (1922) was the first to question the existence of these curious
secondary oscillations on the descending branch of the variable. From his
excellent photographic observations Jordan, 1929), we were able to derive
three different moments of maximum and the moments are given in Table 4.
As RR Leo is relatively bright and the rising branch is very steep the
star is easy to observe and has naturally attracted many observers. As
early as 1929, Nielsen (1929) drew attention to the slow increase in the
period of this star. He gave the elements:
J.D. max. hel. = 2418120.3412 + 0.4523702dxE + 0.275dx10^-9xE^2
Oosterhoff (1930) obtained new sets of very accurate photographic
observations. Having analysed the available data he arrived at the
quadratic term +0.183dx10^-9xE^2. Since Oosterhoff's investigation
several attempts were made to give a more accurate value for the
quadratic term (Tsessevich, 1934, Kooreman, 1935, Gaposchkin, 1934,
Balazs, 1936). Following Oosterhoff's procedure Balazs and Detre (1949)
performed very detailed and precise period analysis. They gave the
formula for the period as follows:
P = 0.45238142d + 0.360dx10^-9xE - 0.7dx10^-6x cos 0.0134deg x (E+6500)
This period satisfied all the observations obtained up to 1949.
A long term periodic change in the period of an RR Lyrae type star is
very interesting because it probably reflects the binary nature of the
variable. The light-time effect can easily be made responsible for this
kind of cyclic variation in the period.
This question seemed very interesting and a great number of photographic
and photoelectric observations have been collected at Konkoly
Observatory during the past 30 years. Since 1952 the star has been
observed photoelectrically almost every year. The photographic plates
were measured by a Cuffey microphotometer and the same comparison stars
were used as by Balazs (1936). Their magnitudes were also adopted from
her measurements. As comparison star we used BD +24deg 2181 (V = 10.400,
B-V = 0.090 and U-B = 0.105 adopted from Kim and Starch, 1967, and
Starch, 1966) to our photoelectric observations (Table 11, 12, Figure 6).
Figure 6: U,B and V light curves of RR Leo
The number of maxima and the time interval now seem to be sufficiently
large for us to make a reasonable period analysis in order to answer the
challenging question raised by the periodic term in the elements. In the
course of the more rigorous period analysis some maxima observed by
Gaposchkin (1934), Sacharov (1953), Soloviev and Shakhovskoj (1958),
Guriev (1937), Ashbrook (1949), Alania (1954), Huth (1964), Ahnert
(1959b, c, 1961), Karetnikov (1961, 1962) and Demjanovskij (1975) should
have been ignored. All of these apart from Gaposchkin's, Alania's, Huth's
and Demjanovskij's observations were made visually. Gaposchkin elaborated
the old Harvard plates which had been obtained with very long exposure times
and sparsely distributed in time. Therefore the maxima given by him have very
low accuracy. Huth worked on the Sonneberg sky patrol plates which had also
been made with fairly long exposure times. Alania's and Demjanovskij's
photographic observations also have very low weight in comparison with the
photoelectric observations obtained at our observatory at about the same time.

Remarks: 1 omitted, 2 redetermined by us, 3 determined by us
The moments of maxima are collected in Table 4. The O-C residuals are
calculated by the linear elements:
J.D. max. hel. = 2430440.3625 + 0.45238172dxE
and plotted against epoch numbers (Figure 7).
A parabolic curve fit yielded the quadratic term:
+1.963dx10^-10xE^2
Figure 7: O-C diagram of RR Leo
The O-C residuals calculated by the quadratic formula clearly show a
cyclic variation which is superimposed on the parabola. Since the time
of maximum can be determined with lower accuracy than that of a well-defined
point of the ascending branch of the light curve we decided to follow
Oosterhoff's and Balazs and Detre's procedure (Oosterhoff, 1930; Balazs
and Detre, 1949). After careful consideration we chose the points on
the ascending branch at the following magnitudes:
m_pg = 10.63 in the case of photographic observations
Deltam = +0.33 in the case of photoelectric observations without filters
DeltaV = +0.194 and DeltaB = +0.326 in the case of photoelectric observations
made in the UBV system
These points correspond to the point defined by Oosterhoff (1930) and used
by Balazs and Detre (1949). The epochs of these points are designated by "t".
In Table 5 the epochs determined by Balazs and Detre (1949, Table 4) are
supplemented with the epochs based on our observations. The error of these
epochs certainly does not exceed 0.0010d. The t-C' residuals in Table 5 have
been calculated by the formula taking into account the quadratic term as well:
C' = 2430440.3385 + 0.45238172dxE + 1.963dx10^-10xE^2
Figure 8 t-C' diagram of RR Leo
The t-C' values plotted against epoch numbers are presented in Figure 8.
Although the cyclic variation is evident we do not have the courage to
fit in a sine curve. The question of the existence. of the sine term in
the elements is open to further discussion and only by new observations
which span at least the next two decades can the final answer be given.

TT LYNCIS
This relatively bright RR Lyrae type variable (TT Lyn = BD +45deg 1669
(9.3) = S 4752 = CSV 1938) was discovered by Hoffmeister (1949) on Sonneberg
plates. Subsequently it was studied visually by Tsessevich (1956) and both
visually and photographically by Ahnert (1959d, 1960a). Tremko (1974)
thoroughly investigated TT Lyn and constructed its light curves in U,B,V and
colour-colour diagram. He made use of nearly 400 photographic and about 4600
photoelectric observations obtained at Skalnate Pleso Observatory (Tremko,
1976). In his discussion he also used the photoelectric observations obtained
at Konkoly Observatory in 1959. The observations were tested for Blazhko-effect
and it was unambiguously shown that TT Lyn has a stable, strictly repetitive
light curve.
Figure 9: B and V light curves of TT Lyn
The star was reobserved at our observatory in 1978. As a comparison star
BD +45deg 1666 was used. Its magnitude and colours V = 9.16, B-V = 0.28
were adopted from a tie-in observation. The observations made at Konkoly
Observatory are given in Table 13.
On J.D. 2443583 the ascending branch was, oddly enough, much steeper
than it used to be (see Figure 9). We have found no explanation for this
strange, unexpected phenomenon. The maximum in phase and height is not shifted,
therefore any Blazhko-effect is out of the question.
Tremko, in his paper mentioned above (1974), gave the list of maxima of
various observers. In the following table we supplement this list with the
maxima obtained from Jones' (1966) and our observations. Sturch's (1966)
observations were insufficient for deriving the time of maximum (Table 6).

The O-C diagram has been constructed using the new elements:
J.D.max. hel. = 2436651.3566 + 0.59743406dxE
Figure 10: O-C diagram of TT Lyn
Yearly means were formed separately from the visual, photographic and
photoelectric observations and plotted against epoch numbers (Figure 10).
The photoelectric maxima can easily be approximated by a straight line and
the new elements were obtained in this way.
AR PERSEI
The discovery of the variability of BD +47deg 965 (9.5)=421.1928 was
announced by Guthnick (1928) and named AR Per by Guthnick and Prager (1930).
Immediately after the discovery Kukarkin (1930) and Lange (1931) investigated
this variable, but Floria (1932a,b) and Beyer (1932,1943) were the first to
determine its correct period using their own visual observations: 0.4255463d
and 0.425551d, respectively.
Long series of visual observations were obtained by Soloviev (1934a, 1935a,
1937, 1939), Kukarkin (1937, 1941, 1949), Lange (1938), Guriev (1938), Miczaika
(1946), Batyrev (1957), Soloviev and Shakhovskoj (1958), Steinman (1958),
Ahnert (1959a, c) and Tsessevich (1966). Alania (1954) and Payne-Gaposchkin
(1954) gave photographic maxima. Tsessevich (1966) examined the Harvard plate
collection and succeeded in determining a great number of maxima between
1900-1950. His observations are unique and make it possible to construct the
O-C diagram of AR Per from the very beginning of this century.
Krygier (1965) also investigated the star photographically but since the
light curve around the maximum was not sufficiently covered by observations
we were not able to determine a time of maximum from his observations.
Since 1954 accurate photoelectric observations are available. Although
Paczynski (1965), Sturch (1966) and Epstein (1969) did not give any moments
of maximum we were able to deduce reliable maxima from their observations.
Geyer (1961) and Fitch et al. (1966) published exact times of maximum for
the years 1958, 1959 and 1964.

Figure 11
At Konkoly Observatory the star was photographically observed in 1937
(Table 15). The comparison stars used are given in Figure 11. From these
observations a maximum could be derived.
The star was first observed photoelectrically in 1954, on J.D. 2435093.
For these observations BD +46deg 860 was used as a comparison star (m_V = 8.75,
B-V = 0.47, U-B = 0.10 adopted from Geyer, 1961). Later on we used
BD +46deg 858 for comparison purposes (V = 9.73, B-V = 0.89, U-B = 0.35 given
by Paczynski, 1965). Our photoelectric observations are given in Table 14 and
presented in Figure 12. The observations made on J.D. 2435093 were shifted by
1.281 in V and by 1.653 in B in the composite light curves.

Remarks: 1 omitted 2 observed by Guthnick 3 rediscussed by Tsessevich
Ahnert (1959a, c) claimed that the star exhibited a Blazhko-effect.
A comparison of the photoelectric light curves made by Geyer (1961),
Paczynski (1965), Fitch et al. (1966) and ourselves (present paper) in the
years 1954,1958,1959,1963,1964,1969 and 1976 is proof of the stable character
of the light variation of AR Per: any kind of light curve variation i.e.
Blazhko-effect is out of the question. Nevertheless the small amplitude of the
light variation as compared with the short period is remarkable.
The list of maxima observed are presented in Table 7. The letter "n"
indicates that the maximum is a normal one. The O-C values were calculated
by the linear formula:
J.D. max. hel. = 2427236.9220 + 0.42554881dxE
Figure 13: O-C diagram of AR Per
The seasonal means are plotted against epoch numbers in Fig. 13.
A quadratic fit of the O-C diagram gives the elements:
J.D. max. hel. = 2427236.9179 + 0.42554892dXE + 1.18dx10^-11xE^2
The steady increase of the period is:
1.18x10^-11 days/cycle = 1.01x10^-8 days/year
Acknowledgements: We are grateful to the late director of the Konkoly
Observatory, Prof. Laszlo Detre, who drew to our attention the problem of
period changes of RR Lyrae stars and encouraged us to begin this work. We are
especially grateful that we have his immense volume of observations at our
disposal. Special thanks go to our colleagues, B. Balazs, K. Gefferth,
M. Lovas, G. Paal and L. Szabados who played a major role in carrying out
observational work. Thanks are also due to other colleagues for telescope
assistance and especially to J. Marton for helping us with the data reduction.
It is also a pleasure to acknowledge those concerned with the preparation
of the manuscript.
