Topic: compact remnants

This lecture introduces neutron stars as compact remnants of stellar explosions. It examines the balance against gravitational collapse, their extreme densities and the observational role of pulsars. The Crab pulsar provides a concrete example, while the possible composition of matter deep inside these objects motivates further research.

This lecture follows massive stars through successive nuclear-burning stages to core collapse. It explains how supernova explosions expel material and enrich the interstellar environment with heavy elements. The discussion then turns to compact remnants, black-hole formation and observational opportunities provided by surviving binary companions.
