Abstract Type : Poster Abstract Category : Stars, The Milky Way Galaxy and its neighbours Abstract : Theoretical studies indicate that contact binaries ultimately form rapidly rotating single-stars merging possibility at (critical mass ratio) q = 0.05-0.09. We accumulated a sample of 143 contact binaries with their mass-ratio, orbital period and filling factor in order to constrain the critical mass-ratio. Our studies show that the critical mass-ratio (q) lies at 0.02 which is much lower than the predicted one. We study the possible consequences of the observed critical mass ratio in the context of merger phenomenon. |
