Aspherical Remnants of Triple and Quadruple Detonations in Binary White Dwarfs
Logan J. Prust, Lars Bildsten, Samuel J. Boos
White dwarfs which explode by the double-detonation mechanism may have a binary white dwarf donor which is subsequently ignited by its collision with the ejecta. This results in th…
Mass Loss and Subsequent Thermal Evolution of Surviving Helium White Dwarfs Shocked by Thermonuclear Supernovae
Tin Long Sunny Wong, Lars Bildsten
Following a type Ia supernova (SN Ia) in a double white dwarf (WD) binary, a surviving WD companion leaves at its orbital velocity ,000 - 3,000 km/s. The Gaia mission ha…
Type IIb Supernova Progenitors in 3D: Variability and Episodic Mass Loss revealed by Radiation-Hydrodynamics Simulations
Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten +1
We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped (, ) Yellow Supergiant (,…
The First Day of a Type Ia Supernova from a Double-Degenerate Binary
Gabriel Kumar, Logan J. Prust, Lars Bildsten
Supernovae in binary star systems involve a hydrodynamical interaction between the ejecta and a binary companion. This collision results in shock heating and a modified density str…
Wakes from Companion Interactions in Type Ia Supernovae Nebular Emission Line Profiles
Kathlynn Simotas, Lars Bildsten, Logan J. Prust
Thermonuclear supernovae (SNe) are the result of the nuclear transformation of carbon/oxygen (C/O) white dwarfs (WDs) to the radioactive element and intermediate…
Stochastic low-frequency variability of 50 massive stars in the Cygnus OB associations and the Small Magellanic Cloud
M. G. Pedersen, L. Bildsten
In recent years, high-precision high-cadence space photometry has revealed that stochastic low frequency (SLF) variability is common in the light curves of massive stars. We use th…
