Abstract: The explosion mechanism of Type Ia supernovae (SN Ia) is unknown. The continuity in the properties of SNe Ia across the luminosity function suggests a single dominant channel to explain the population. We argue that direct collisions of white dwarfs may be promising as such a major channel. I will present results of our efforts to test the collision model.
Bio: Subo Dong has been a faculty member of Kavli Institute for Astronomy & Astrophysics (KIAA) at Peking University since 2013. He received his B.Sc. in astronomy from Nanjing University in 2004, and he obtained his Ph.D. in astronomy from the Ohio State University in 2009. Then he was awarded the inaugural NASA Carl Sagan Fellowship for exoplanet research and was a postdoctoral fellow at the Institute for Advanced Study, Princeton. His research interests include understanding how supernovae explode, studying the distribution and dynamical evolution of extrasolar planets and searching for planets and black holes with gravitational microlensing.
