Characterizing Massive Black Holes through Stellar Tidal Disruption
  Astronomy and astrophysics

Speaker : Enrico Ramirez-Ruiz (UC Santa Cruz)
Abstract : A star interacting with a massive black hole cannot be treated as a point mass if its gets o close to the black hole that it becomes vulnerable to tidal distortions and even disruption. When a rapidly changing tidal force starts to compete with a star’s self-gravity, the material of the star responds on a complicated way. This phenomenon poses an as yet unmet challenge to computer simulations. The art of modeling the tidal disruption of stars by massive black holes forms the main theme of my talk. Detailed simulations should tell us what happen when stars of different types get tidally disrupted, and what radiation a distant observer might detect as the observational signature of such events.
