Delayed Circumstellar Interaction for Type Ia SN 2015cp Revealed by an HST Ultraviolet Imaging Survey
M. L. Graham, C. E. Harris, P. E. Nugent +11
The nature and role of the binary companion of carbon-oxygen white dwarf stars that explode as Type Ia supernovae (SNe Ia) are not yet fully understood. Past detections of circumst…
Don't Blink: Constraining the Circumstellar Environment of the Interacting Type Ia Supernova 2015cp
C. E. Harris, P. E. Nugent, A. Horesh +12
Despite their cosmological utility, the progenitors of Type Ia supernovae (SNe Ia) are still unknown, with many efforts focused on whether accretion from a nondegenerate companion…
A Search For Pulsations in the Optical Light Curve of the Nova ASASSN-17hx
Lee J. Rosenthal, Ken J. Shen, Gregg Hallinan +4
We present high-speed optical observations of the nova ASASSN-17hx, taken both immediately after its discovery and close to its first peak in brightness, to search for seconds -- m…
Quantifying How Density Gradients and Front Curvature Affect Carbon Detonation Strength During Type Ia Supernovae
Broxton J. Miles, Dean M. Townsley, Ken J. Shen +2
Accurately reproducing the physics behind the detonations of Type Ia supernovae and the resultant nucleosynthetic yields is important for interpreting observations of spectra and r…
Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-Degenerate Double-Detonation Type Ia Supernovae
Ken J. Shen, Douglas Boubert, Boris T. Gänsicke +23
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progeni…
