Topic: massive stars

This seminar follows massive stars that evolve in close pairs. Changes in their structure can initiate mass transfer, producing bright X-ray emission and altering their later evolution. The presentation connects these interactions to the mergers and energetic end stages of binary systems.

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.
