Journal ArticleDOI
G-Mode Excitation During the Pre-explosive Simmering of Type Ia Supernovae
TL;DR: In this paper, the authors estimate the excitation of g-modes by convection during a white dwarf supernova and explore their possible effect on the WD, showing that the WD's surface temperature increases by ≈4 × 10^8 K, which is sufficient to ignite a layer of helium, as is expected to exist for some SN Ia scenarios.
Journal ArticleDOI
Turbulent Mixing on Helium-Accreting White Dwarfs
TL;DR: In this article, a combination of semi-analytic and simple numerical models was used to explore when turbulent mixing due to hydrodynamic instabilities during the accretion process can mix C/O core material up into the accreted helium.
Journal ArticleDOI
A Speed Bump: SN 2021aefx Shows that Doppler Shift Alone Can Explain Early Excess Blue Flux in Some Type Ia Supernovae

TL;DR: In this article , the early excess blue flux may be due to a rapid change in spectral velocity in the first few days post explosion, produced by the emission of the Ca ii H&K feature passing from the u to the B bands on the timescale of a few days.
Journal ArticleDOI
Inferring the Presence of Tides in Detached White Dwarf Binaries
TL;DR: In this article, the first and second derivative of the orbital period and braking index of a binary was analyzed to infer the degree of tidal locking on the binary, and the deviations between a binary evolving under the influence of only GW emission and a binary that is also experiencing some degree of locking.
