Abstract:
We investigated the role of trigger mechanisms in the low mass star formation process. Star bearing and pre-protostellar cloud cores were searched as very cold objects of the ISO Serendipity Survey. We compared the distribution of cold starless cores VCCs to the distribution of FIR loops found on IRAS images. The distribution of VCCs follows the large scale ISM density distribution described by the FIR loops. Assuming that the 30pc-200pc scale trigger effects are reflected in the loop/shell structures, this result suggest a link between these effects and the VCCs.
