Oral Presentation
Statistical properties of interacting binary stars with MESA
Presenter: Sung-Han Tsai (NCU/ASIAA)
Observational evidence suggests that about 50% of massive stellar systems are binary instead of single star. However, many binary stars cannot be resolved even in 10-m class telescopes due to the small separation between two stars. Inside close binaries, post-main sequence stars can easily interact with each other through a significant mass-transfer. Such interactions can dramatically affect the luminosities, evolution tracks, and fates of the binaries. We use MESA code to simulate the binary stellar evolution and vary the physical parameters such as the stellar mass/metallicity and the binary separation to create a suite of 300+ models so that the samples are large enough to make the statistical analysis. In this talk, I will present the results of my binary models and discuss the physical properties of interacting binaries.
