ASTROPHYSICS:
When a White Dwarf Explodes

David Branch

Type Ia supernova explosions are caused by the complete thermonuclear disruption of a white dwarf. Model studies attempting to elucidate the explosion mechanism have been limited to spherically symmetric one-dimensional models. In his Perspective, Branch highlights the three-dimensional model reported by Gamezo et al. Despite its limitations, the study heralds a new era of model complexity in supernova studies.
