Description
Title：Massive Star Formation through the Universe - from Orion to the first black holes
Speaker：Jonathan C. Tan (University of Virginia and Chalmers University)
Abstract：Massive stars, those with greater than eight times the mass of the Sun, influence the universe in profound ways. They are powerful sources of light, winds, and supernova explosions that physically and chemical transform galactic and intergalactic space. The birth of our own solar system and most others appear to be impacted by massive stars. There may also be an intriguing link between the origin of supermassive black holes and the formation of the first generation of massive stars under the influence of dark matter annihilation. In this talk I discuss the physics of massive star formation and consider cases of how it is occurring in our Galaxy and how it may have differed in the very early universe.
