Proton-Rich Nuclear Statistical Equilibrium
I. R. Seitenzahl, F. X. Timmes, A. Marin-Laflèche +3
Proton-rich material in a state of nuclear statistical equilibrium (NSE) is one of the least studied regimes of nucleosynthesis. One reason for this is that after hydrogen burning,…
Study of the Detonation Phase in the Gravitationally Confined Detonation Model of Type Ia Supernovae
Casey A. Meakin, Ivo Seitenzahl, Dean Townsley +3
We study the gravitationally confined detonation (GCD) model of Type Ia supernovae through the detonation phase and into homologous expansion. In the GCD model, a detonation is tri…
Capturing the Fire: Flame Energetics and Neutronizaton for Type Ia Supernova Simulations
A. C. Calder, D. M. Townsley, I. R. Seitenzahl +6
We develop and calibrate a realistic model flame for hydrodynamical simulations of deflagrations in white dwarf (Type Ia) supernovae. Our flame model builds on the advection-diffus…
Discovery of A New Class of Pulsating Stars: Gravity-mode Pulsators among Subdwarf B Stars
E. M. Green, G. Fontaine, M. D. Reed +15
During the course of an ongoing CCD monitoring program to investigate low-level light variations in subdwarf B (sdB) stars, we have serendipitously discovered a new class of low am…
