| Abstract: |
Luminous red novae are astrophysical transients thought to be caused by the merging of two stars in close binary systems. In this study, we presented a period study of contact binary merger candidates in the Galactic bulge. In order to identify the potential stellar merger candidates, we selected the 132 contact eclipse binaries with a high decreasing rate of P ̇ ≤ −3×10−6 day yr−1 in the Galactic bulge from the literature. The observational data was obtained using the Korea Microlensing Telescope Network and its 1.6 m telescopes (CTIO, SAAO, and SSO). The period study of the selected binary system was analyzed using the O − C diagrams. |
