Research Abstract |
Type Ia supernovae (SNe Ia) are thermonuclear explosions of a white dwarf. In this research, (1) I calculated nuclear reactions in SNe Ia and studied a role of type Ia as the origin of some elements in the Universe, and (2) provided an observational method to clarify how the thermonuclear sparks are ignited within a white dwarf. (3) Based on this prediction, I examined available observational data and showed that the ignition generally starts at an offset from the center of a white dwarf. (4) I further proved that this asymmetry is the origin of a mysterious diversity in SNe Ia. These results have various implications for the supernova cosmology. These provide breakthroughs in the related fields since these findings can solve several unresolved issues by a single, unified scenario.
