Explore the complex dynamics of stellar evolution near massive black holes in this astronomy seminar presented by Eliot Quataert from Princeton University. Delve into the inevitable inspiral process that occurs when stars orbit sufficiently close to massive black holes due to gravitational wave radiation, examining the intricate interplay between tidal heating, mass transfer mechanisms, and potential collisions with ambient accretion disks. Discover how these processes determine stellar fates and their connection to recently observed enigmatic transient phenomena in galactic nuclei, including partial tidal disruption events and quasi-periodic eruptions (QPEs). Learn about the broader context of stellar dynamics in galactic nuclei, covering relationships to observed orbiting stars in the Galactic Center, extreme mass ratio inspirals detectable by LISA, hyper-velocity star formation, and traditional tidal disruption events. Gain insights into cutting-edge astrophysical research that bridges theoretical stellar dynamics with observational astronomy, providing a comprehensive understanding of one of the most extreme environments in the universe where stellar matter encounters supermassive black holes.
