Abstract Type Ia supernovae (SNe Ia) play a key role in the fields of astrophysics and
cosmology. It is widely accepted that SNe Ia arise from thermonuclear explosions of white …

Motivated by the fact that calibrated light curves of Type Ia supernovae (SNe Ia) have
become a major tool to determine the expansion history of the Universe, considerable …

We present results for a suite of 14 three-dimensional, high-resolution hydrodynamical
simulations of delayed-detonation models of Type Ia supernova (SN Ia) explosions. This …

We investigate whether pure deflagration models of Chandrasekhar-mass carbon–oxygen
white dwarf stars can account for one or more subclass of the observed population of Type …

The first γ-ray line originating from outside the Solar System that was ever detected is the
511 keV emission from positron annihilation in the Galaxy. Despite 30 years of intense …

We present 32 epochs of optical (3300− 9700 Å) spectrophotometric observations of the
nearby quintessential “normal” type Ia supernova (SN Ia) SN 2011fe in the galaxy M101 …

In our quest to identify the progenitors of Type Ia supernovae (SNe Ia), we first update the
nucleosynthesis yields for both near-Chandrasekhar-(Ch) and sub-Ch-mass white dwarfs …

The nearby supernova SN 2011fe can be observed in unprecedented detail. Therefore, it is
an important test case for Type Ia supernova (SN Ia) models, which may bring us closer to …

Context. The origin of subluminous Type Ia supernovae (SNe Ia) has long eluded any
explanation, because all Chandrasekhar-mass models have severe problems reproducing …
