The role of dredge-up in double white dwarf mergers
Jan E. Staff, Brandon Wiggins, Dominic Marcello +6
We present the results of an investigation of the dredge-up and mixing during the merger of two white dwarfs with different chemical compositions by conducting hydrodynamic simulat…
56Ni Production in Double Degenerate White Dwarf Collisions
Cody Raskin, Evan Scannapieco, Gabriel Rockefeller +3
We present a comprehensive study of white dwarf collisions as an avenue for creating type Ia supernovae. Using a smooth particle hydrodynamics code with a 13-isotope, α-chain nucle…
Spectra of Type Ia Supernovae from Double Degenerate Mergers
Chris L. Fryer, Ashley J. Ruiter, Krzysztof Belczynski +13
The merger of two white dwarfs (a.k.a. double degenerate merger) has often been cited as a potential progenitor of type Ia supernovae. Here we combine population synthesis, merger…
Prompt Ia Supernovae Are Significantly Delayed
Cody Raskin, Evan Scannapieco, James Rhoads +1
The time delay between the formation of a population of stars and the onset of type Ia supernovae (SNe Ia) sets important limits on the masses and nature of SN Ia progenitors. Here…
On Type Ia Supernovae From The Collisions of Two White Dwarfs
Cody Raskin, F. X. Timmes, Evan Scannapieco +2
We explore collisions between two white dwarfs as a pathway for making Type Ia Supernovae (SNIa). White dwarf number densities in globular clusters allow 10-100 redshift <1 collisi…
