Binary and Multiple Stars

The video explores the concept of binary stars, which are stars gravitationally bound together. It distinguishes between optical double stars and binary stars, explaining various types such as visual, spectroscopic, eclipsing, and contact binaries. The video highlights the importance of binary stars in understanding stellar masses and astrophysics. It also discusses phenomena like stellar novae and supernovae, emphasizing the role of white dwarfs and mass transfer in these explosive events.
