Radio Observations of Six Young Type Ia Supernovae
C. E. Harris, Sumit K. Sarbadhicary, L. Chomiuk +3
Type Ia supernovae (SNe Ia) are important cosmological tools, probes of binary star evolution, and contributors to cosmic metal enrichment; yet, a definitive understanding of the b…
A Low-Mass Helium Star Progenitor Model for the Type Ibn SN 2020nxt
Qinan Wang, Anika Goel, Luc Dessart +55
A growing number of supernovae (SNe) are now known to exhibit evidence for significant interaction with a dense, pre-existing, circumstellar medium (CSM). SNe Ibn comprise one such…
A radio-detected Type Ia supernova with helium-rich circumstellar material
Erik C. Kool, Joel Johansson, Jesper Sollerman +34
Type Ia supernovae (SNe Ia) are thermonuclear explosions of degenerate white dwarf (WD) stars destabilized by mass accretion from a companion star, but the nature of their progenit…
The Absolute Magnitudes of 1991T-like Supernovae
M. M. Phillips, C. Ashall, Christopher R. Burns +20
1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H &…
Seven years of coordinated Chandra-NuSTAR observations of SN2014C unfold the extreme mass-loss history of its stellar progenitor
Daniel Brethauer, Raffaella Margutti, Danny Milisavljevic +13
We present the results from our seven-year long broad-band X-ray observing campaign of SN\,2014C with \emph{Chandra} and \emph{NuSTAR}. These coordinated observations represent the…
Tumbling Dice: Radio Constraints on the Presence of Circumstellar Shells around Type Ia Supernovae with Impact Near Maximum Light
Chelsea E. Harris, Laura Chomiuk, Peter E. Nugent
The progenitors of Type Ia supernovae (SNe Ia) are debated, particularly the evolutionary state of the binary companion that donates mass to the exploding carbon-oxygen white dwarf…
