3D Hydrodynamical Simulations of Helium-Ignited Double-degenerate White Dwarf Mergers
Niranjan Roy, Vishal Tiwari, Alexey Bobrick +6
The origins of type Ia supernovae (SNe Ia) are still debated. Some of the leading scenarios involve a double detonation in double white dwarf (WD) systems. In these scenarios, heli…
The Differences between Analytical and Numerical Ignition Curve of He-C-O Mixture
Rahul Kashyap
In this paper, we use large reaction networks to find ignition conditions of single-zone nuclear fuel with compositions typical of white dwarf (WD) matter. The necessary but, possi…
Can Kilonova Light curves be Standardized?
Rahul Kashyap, Gayathri Raman, Parameswaran Ajith
Binary neutron star mergers have been recently confirmed to be the progenitors of the optical transients kilonovae (KNe). KNe are powered by the radioactive decay of neutron-rich e…
Double-Degenerate Carbon-Oxygen and Oxygen-Neon White Dwarf Mergers: A New Mechanism for Faint and Rapid Type Ia Supernovae
Rahul Kashyap, Tazkera Haque, Pablo Lorén-Aguilar +2
Type Ia supernovae (SNe Ia) originate from the thermonuclear explosion of carbon-oxygen white dwarfs (CO WDs), giving rise to luminous optical transients. A relatively common varie…
Constraining The Single-Degenerate Channel of Type Ia Supernovae With Stable Iron-Group Elements in SNR 3C 397
Pranav Dave, Rahul Kashyap, Robert Fisher +3
Recent Suzaku X-ray spectra of SNR 3C 397 indicate enhanced stable iron-group element abundances of Ni, Mn, Cr, and Fe. Seeking to address key questions about the progenitor and ex…
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…
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…
