[post_content] => Abstract: When a wandering star comes close enough to a black hole, it can be ripped apart by tidal forces, resulting in partial or complete destruction. Such tidal disruption events not only provide fascinating pictures of the stellar interior, but is also a theoretical laboratory to understand the physics of strong gravity. This is even richer in the presence of spins -- both of the star and the black hole. In this talk we will explore aspects of black holes interactions with stars and argue why these are of fundamental importance in astrophysics. We identify various interesting phenomena via numerical experiments and discuss their physical explanations.
About the Speaker: Dr. Tapobrata Sarkar is a professor of physics at IIT Kanpur. He obtained his doctoral degree in theoretical high energy physics at the Institute of Mathematical Sciences, Chennai. Subsequently he carried out postdoctoral research at the Tata Institute of Fundamental Research (TIFR), Mumbai and the International Centre for Theoretical Physics (ICTP), Trieste, Italy.
He is a theoretical physicist whose research interests lie in the study of Information Geometry and Complexity, Classical and Quantum Phase Transitions, Classical and Quantum Gravity and astrophysical black holes.
We look forward to your active participation.
