Description
The recent resurgence of intensity interferometry through instruments like VERITAS, MAGIC, HESS, and the ASTRI array has opened new pathways for achieving beyond milli-arcsecond-scale imaging of massive and evolved stars, including OB-type, Wolf-Rayet, and pulsating stars in complex stellar systems using optical wavelengths. Among these, close binary stars continue to fascinate astronomers due to their dynamic interactions and complex evolutionary pathways. Tidal forces between the components of such systems play a significant role in shaping their physical evolution, influencing stellar rotation and mass transfer. In this presentation, I will focus on the tidal deformation simulation in massive close binary systems and explore how such stretching impacts the square visibility function on the observational plane. Estimation of these tidal interactions not only informs binary stellar evolution models but also sheds light on the internal dynamics and distorted surface geometries of such stars, contributing to a deeper understanding of stellar astrophysics.
