Explore the fascinating world of supernovae and neutron stars in this comprehensive lecture by G Srinivasan from the International Centre for Theoretical Sciences. Delve into the history of guest stars, the groundbreaking work of Baade and Zwicky, and Landau's invention of neutron stars. Examine the physics behind massive star evolution, core collapse, and supernova explosions. Learn about neutrino processes, supernova light curves, and the famous 1987 supernova in the Large Magellanic Cloud. Investigate various types of supernovae, including Type Ia, and explore stunning images of supernova remnants captured by the Chandra X-ray Observatory. Gain insights into the violent interstellar medium and the interaction between supernova bubbles and interstellar clouds. Conclude with a preview of the next lecture on the interior of neutron stars, followed by a Q&A session.
