One-Armed Spiral Instability in Double-Degenerate Post-Merger Accretion Disks
Rahul Kashyap, Robert Fisher, Enrique García-Berro +3
Increasing observational and theoretical evidence points to binary white dwarf mergers as the origin of some if not most normal Type Ia supernovae (SNe Ia). In this paper, we discu…
White dwarf dynamical interactions and fast optical transients
Enrique García-Berro, Carles Badenes, Gabriela Aznar-Siguán +1
Recent advances in time-domain astronomy have uncovered a new class of optical transients with timescales shorter than typical supernovae and a wide range of peak luminosities. Sev…
Spiral Disk Instability Can Drive Thermonuclear Explosions in Binary White Dwarf Mergers
Rahul Kashyap, Robert Fisher, Enrique García-Berro +3
Thermonuclear, or Type Ia supernovae (SNe Ia), originate from the explosion of carbon--oxygen white dwarfs, and serve as standardizable cosmological candles. However, despite their…
The response of a helium white dwarf to an exploding type Ia supernova
Oded Papish, Noam Soker, Enrique García-Berro +1
We conduct numerical simulations of the interacting ejecta from an exploding CO white dwarf (WD) with a He WD donor in the double-detonation scenario for Type Ia supernovae (SNe Ia…
Detonations in white dwarf dynamical interactions
Gabriela Aznar-Siguán, Enrique García-Berro, Pablo Lorén-Aguilar +2
In old, dense stellar systems collisions of white dwarfs are a rather frequent phenomenon. Here we present the results of a comprehensive set of Smoothed Particle Hydrodynamics sim…
