Explosions of O-Ne-Mg cores, the Crab supernova, and subluminous type II-P supernovae
We present results of simulations of stellar collapse and explosions in spherical symmetry for progenitor stars in the 8–$10\,M_\odot$ range with an O-Ne-Mg core. The simulations were continued until…
A Common Explosion Mechanism for Type Ia Supernovae
A systematic spectral analysis of a large sample of well-observed type Ia supernovae finds that allsupernovae have low-velocity cores of stable iron-group elements and suggests that their progenitors had the same mass.
Type IA Supernova Explosion Models
▪ Abstract Because calibrated light curves of type Ia supernovae have become a major tool to determine the local expansion rate of the universe and also its geometrical structure, considerable atte...
NORMAL TYPE Ia SUPERNOVAE FROM VIOLENT MERGERS OF WHITE DWARF BINARIES
One of the most important questions regarding the progenitor systems of Type Ia supernovae (SNe Ia) is whether mergers of two white dwarfs can lead to explosions that reproduce observations of normal…

A simulation of the merger of two equal-mass white dwarfs that leads to a sub-luminous explosion, although at the expense of requiring a single common-envelope phase, and component masses of ∼0.9M⊙.
Spectrophotometric time series of SN 2011fe from the Nearby Supernova Factory
We present 32 epochs of optical (3300‐9700 A) spectrophotometric observations of the nearby quintessential “normal” type Ia supernova (SN Ia) SN 2011fe in the galaxy M101, extending from 15 to + 97 d…
DETONATIONS IN SUB-CHANDRASEKHAR-MASS C+O WHITE DWARFS
Explosions of sub-Chandrasekhar-mass white dwarfs (WDs) are one alternative to the standard Chandrasekhar-mass model of Type Ia supernovae (SNe Ia). They are interesting since binary systems with…

Extensive HST ultraviolet spectra and multiwavelength observations of SN 2014J in M82 indicate reddening and circumstellar scattering by typical dust
SN 2014J in M82 is the closest detected Type Ia supernova (SN Ia) in at least 28 years and perhaps in 410 years. Despite its small distance of 3.3 Mpc, SN 2014J is surprisingly faint, peaking at V =…
Three-dimensional delayed-detonation models with nucleosynthesis for Type Ia supernovae
We present results for a suite of fourteen three-dimensional, high resolution hydrodynamical simulations of delayed-detonation models of Type Ia supernova (SN Ia) explosions. This model suite…
