High -ray escape time in 2003fg-like supernovae: A challenge to proposed models
Amir Sharon, Doron Kushnir, Eden Schinasi-Lemberg
A rare subclass of Type Ia supernovae (SNe Ia), named after the prototype SN 2003fg, includes some of the brightest SNe Ia, often called "super Chandrasekhar-mass" SNe Ia. We calcu…
All known Type Ia supernovae models fail to reproduce the observed bolometric luminosity-width correlation
Amir Sharon, Doron Kushnir, Nahliel Wygoda
Type Ia supernovae (SNe Ia) are widely believed to arise from thermonuclear explosions of white dwarfs (WDs). However, ongoing debate surrounds their progenitor systems and the mec…
A 12.4 day periodicity in a close binary system after a supernova
Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37
Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…
1100 days in the life of the supernova 2018ibb -- The best pair-instability supernova candidate, to date
Steve Schulze, Claes Fransson, Alexandra Kozyreva +63
Abridged - Stars with ZAMS masses between 140 and are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce…
The -ray deposition histories of Calcium-rich supernovae
Amir Sharon, Doron Kushnir
Calcium-rich supernovae (Ca-rich SNe) are faint, rapidly evolving transients whose progenitor system is yet to be determined. We derive the -ray deposition histories of five Ca-…
SN 2022oqm -- a Ca-rich explosion of a compact progenitor embedded in C/O circumstellar material
I. Irani, Ping Chen, Jonathan Morag +27
We present the discovery and analysis of SN\,2022oqm, a Type Ic supernova (SN) detected \,day after explosion. The SN rises to a blue and short-lived (2\,days) initial peak. Ea…
