A meta-analysis of core-collapse supernova 56Ni masses

JP Anderson - Astronomy & Astrophysics, 2019 - aanda.org
Context. A fundamental property determining the transient behaviour of core-collapse

A Gagliano, L Izzo, CD Kilpatrick… - The Astrophysical …, 2022 - iopscience.iop.org
We present photometric and spectroscopic observations of Supernova 2020oi (SN 2020oi),
a nearby (∼ 17 Mpc) type-Ic supernova (SN Ic) within the grand-design spiral M100. We …

The nickel mass distribution of stripped-envelope supernovae: implications for additional power sources

N Afsariardchi, MR Drout, DK Khatami… - The Astrophysical …, 2021 - iopscience.iop.org
We perform a systematic study of the 56 Ni mass (M Ni) of 27 stripped-envelope supernovae
(SESNe) by modeling their light-curve tails, highlighting that use of" Arnett's rule" …

Spectrophotometric templates for core-collapse supernovae and their application in simulations of time-domain surveys

M Vincenzi, M Sullivan, RE Firth… - Monthly Notices of …, 2019 - academic.oup.com
The design and analysis of time-domain sky surveys require the ability to simulate
accurately realistic populations of core-collapse supernova (SN) events. We present a set of …
