Description
Binary star interactions play a critical role in shaping the circumstellar medium (CSM) and influencing the observational properties of supernovae (SNe). This study focuses on the mass-loss processes in interacting binary stars with solar-like metallicity, particularly in the Case C systems where mass transfer occurs during the donor star's secondary expansion phase, which follows helium ignition. Using the MESA stellar evolution code, we simulate binary stars across a grid of donor star masses and orbital separations. We aim to understand the mass transfer dynamics, the resulting CSM structures, and their influence on SNe progenitor classifications. This project combines numerical simulations with observational results, comparing SNe observations with our models and interpreting the resulting CSM properties. The outcomes will provide a comprehensive framework linking binary stellar evolution, mass-loss mechanisms, and SNe diversity, offering new insights into the physics of interacting supernovae.
