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…
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…
Ejecta Wakes from Companion Interaction in Type Ia Supernova Remnants
Logan J. Prust, Gabriel Kumar, Lars Bildsten
Type Ia supernovae are triggered by accretion onto a white dwarf from a companion which is most likely Roche lobe-filling at the time of the explosion. The collision between the ej…
Morphology and Mach Number Dependence of Subsonic Bondi-Hoyle Accretion
Logan J. Prust, Hila Glanz, Lars Bildsten +2
We carry out three-dimensional computations of the accretion rate onto an object (of size and mass ) as it moves through a uniform medium at a subsonic speed $v_{…
An outburst from a massive star 40 days before a supernova explosion
E. O. Ofek, M. Sullivan, S. B. Cenko +17
Various lines of evidence suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as a supernova. Interestingly, several models predict su…
X-ray emission from supernovae in dense circumstellar matter environments: A search for collisionless shocks
E. O. Ofek, D. Fox, S. B. Cenko +21
(Abridged). The optical light curve of some SNe may be powered by the outward diffusion of the energy deposited by the explosion shock in optically thick circumstellar matter (CSM)…
Supernova PTF 09uj: A possible shock breakout from a dense circumstellar wind
E. O. Ofek, I. Rabinak, J. D. Neill +29
Type-IIn supernovae (SNe), which are characterized by strong interaction of their ejecta with the surrounding circumstellar matter (CSM), provide a unique opportunity to study the…
