Difficulties of two exploding white dwarfs to account for type Ia supernovae with bimodal nebular emission profiles

We use a simple dynamical scheme to simulate the ejecta of type Ia supernova (SN Ia) scenarios with two exploding white dwarfs (WDs) and find that the velocity distribution of the ejecta has difficulties accounting for bimodal emission line profiles

The runaway velocity of the white dwarf companion in the double detonation scenario of supernovae

Autor: Braudo, Jessica, Soker, Noam

Publikováno v: The Open Journal of Astrophysics, vol. 7, id. 7, 2024

We consider the finite velocity of the ejecta of a type Ia supernova (SN Ia) in the double detonation (DDet) scenario with a white dwarf (WD) mass-donor companion, and find that the runaway velocity of the surviving (mass donor) WD is lower than its

Accretion induced merger leading to core collapse supernovae in old stellar populations

Autor: Braudo, Jessica, Bear, Ealeal, Soker, Noam

We examine a triple-star evolution that might lead to core collapse supernovae (CCSNe) in stellar populations that are too old to allow for single or binary evolution to form CCSNe, i.e., where the most massive stars that evolve off the main sequence
