This lecture delves into the fascinating world of intrinsic stellar variability, focusing on expulsions from stars rather than explosions. The instructor discusses phenomena observed in stars, such as chromatic changes in eclipsing binaries and the classification of variable stars. The lecture explores the unique characteristics of BE stars, UV setting stars, and welfare stars, shedding light on eruptive types in star evolution. Furthermore, the discussion extends to the enigmatic behavior of Betelgeuse, a supergiant star exhibiting rapid dimming events. The lecture also touches upon the intriguing case of Arc Coronae Borealis stars, known for their irregular fadings and low amplitude pulsations. Through detailed analysis and observational evidence, the lecture provides insights into the complex processes governing the variability and evolution of stars.
