Contact Binaries Towards Merging (CoBiToM) Project is an optical monitoring program, initiated in summer 2012 by Dr. Kosmas Gazeas at the University of Athens, in order to investigate the orbital period cut-off of contact binaries (~0.22 days). The program utilizes various telescopes, in order to cover the bright and faint magnitude limit on the targets. High accurate multi-color photometric observations of contact binaries with very short orbital period are studied, in order to investigate the stellar evolution just before merging process.
