How Stars Destroy Each Other
Summary
This episode explores the violent dynamics of binary star systems, tracing the evolution from classical novae like the 1437 "guest star" to extreme X-ray binaries involving neutron stars and black holes. It details how compact objects siphon matter from companions, creating phenomena such as pulsars, black widow systems, and Type Ia supernovae. The segment concludes with a Q&A addressing LIGO's detection of a merger involving an object of ambiguous mass, discussing the physics of event horizons and the possibility of primordial black holes.
