Three Colour Photometry of W CVn, Light Curve and Period
No. 67
Budapest, 1974
Abstract
Three colour photoelectric observations of the variable W CVn obtained
at Konkoly Observatory and at Skalnate Pleso Observatory were interpreted.
The investigation shows secular change of the period and a stable light curve.
The interstellar absorption in the direction of variable is discussed
and the absolute magnitude from the period-luminosity relation
was derived. Colour-colour diagram was constructed and distance
of 980 pc for the variable was determined.
