Ground-based and JWST Observations of SN 2022pul. II. Evidence from Nebular Spectroscopy for a Violent Merger in a Peculiar Type Ia Supernova

The Astrophysical Journal
We present an analysis of ground-based and JWST observations of SN 2022pul, a peculiar “03fg-like” (or “super-Chandrasekhar”) Type Ia supernova (SN Ia), in the nebular phase at 338 days postexplosion.

Modeling detonations in type Ia supernovae [PDF]

, 2010
The explosion mechanism and the progenitor systems of Type Ia supernovae are still under debate. In this thesis, detailed multidimensional hydrodynamic simulations are carried out to promote the theoretical understanding of currently discussed models for Type Ia supernovae.
