S. Chandrasekhar : White Dwarfs, H− ion,.., Black holes, Gravitational waves
Patrick Das Gupta
This is a concise review of S. Chandrasekhar’s research contributions to astrophysics, ranging from his early studies on white dwarfs using relativistic quantum statistics to topics as diverse as dynamical friction, negative hydrogen ion, fluid dynamical instabilities, black holes and gravitational waves. The exposition is based on simple physical explanations in the context of observational astronomy, addressed primarily to the undergraduate students. Black holes and their role as central engines of active, compact, high energy sources have been discussed in some details.
