Science Results - Surface Helium Detonation Spells End for White Dwarf University of Tokyo/NAOJ

Using Hyper Suprime-Cam mounted on the Subaru Telescope, the team detected a type Ia supernova within a day after the explosion, and explained its behavior through a model calculated using the supercomputer ATERUI.
