Observational signatures of thermonuclear electron-capture supernovae -- Ne II line strengthening and color evolution as traces of the explosion mechanism
Alexander Holas, Fionntan P. Callan, Samuel W. Jones +7
Thermonuclear electron-capture supernovae (tECSNe) are a potential fate of certain intermediate mass stars forming ONe cores at the end of their evolution. Simulations suggest that…
SN 2020pvb: a Type IIn-P supernova with a precursor outburst
Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37
We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…
Thermonuclear explosions as Type II supernovae
Alexandra Kozyreva, Javier Moran-Fraile, Alexander Holas +5
We consider a binary stellar system, in which a low-mass, of 0.6 Msun, carbon-oxygen white dwarf (WD) mergers with a degenerate helium core of 0.4 Msun of a red giant. We analyse t…
StaNdaRT: A repository of standardized test models and outputs for supernova radiative transfer
Stéphane Blondin, Sergei Blinnikov, Fionntan P. Callan +26
We present the first results of a comprehensive supernova (SN) radiative-transfer (RT) code-comparison initiative (StaNdaRT), where the emission from the same set of standardized t…
Low-luminosity type IIP supernovae: SN 2005cs and SN 2020cxd as very low-energy iron core-collapse explosions
Alexandra Kozyreva, Hans-Thomas Janka, Daniel Kresse +2
SN 2020cxd is a representative of the family of low-energy, underluminous Type IIP supernovae (SNe), whose observations and analysis were recently reported by Yang et al. (2021). H…
Synthetic observables for electron-capture supernovae and low-mass core collapse supernovae
Alexandra Kozyreva, Petr Baklanov, Samuel Jones +2
Stars in the mass range from 8 to 10 solar masses are expected to produce one of two types of supernovae (SNe), either electron-capture supernovae (ECSNe) or core-collapse supernov…
Pair-Instability Supernova Simulations: Progenitor Evolution, Explosion, and Light Curves
Matthew S. Gilmer, Alexandra Kozyreva, Raphael Hirschi +2
In recent years, the viability of the pair-instability supernova (PISN) scenario for explaining superluminous supernovae has all but disappeared except for a few slowly-evolving ex…
Effects of Dimensionality on Pair-Instability Supernova Explosions
Matthew S. Gilmer, Alexandra Kozyreva, Raphael Hirschi +1
Since the emergence of the new class of extremely bright transients, super-luminous supernovae (SLSNe), three main mechanisms to power their light curves (LCs) have been discussed.…
On the nature and detectability of Type Ib/c supernova progenitors
S. -C. Yoon, G. Graefener, J. S. Vink +2
The progenitors of many Type II supernovae have been observationally identified but the search for Type Ibc supernova (SN Ibc) progenitors has thus far been unsuccessful, despite t…
