Abstract Type : Poster Abstract Category : Stars,ISM and the Galaxy Abstract : First photometric investigation of nine ultra-short period eclipsing binaries detected in OGLE (Optical Gravitational Lensing Experiment) fields present towards the galactic bulge are reported. Binaries of such ultra-short periods have been rarely studied and understanding their existence can infer their formation and evolutionary scenario which can be either due to loss of angular momentum through magnetized winds or due to any other mechanism. The light curve analysis was carried out using PHOEBE, based on Wilson-Devinney program. The best solutions obtained indicate that these binaries are cool high-mass ratio eclipsing systems. The structure and evolutionary state of these short period binaries is discussed in this work, which would pave-way in building new binary models to explore the origin and evolution of such rare class systems that remains poorly understood.
