Binary progenitor systems for Type Ic supernovae [PDF]

Nature Communications
Core-collapse supernovae are explosions of massive stars at the end of their evolution. They are responsible for metal production and for halting star formation, having a significant impact on galaxy evolution.

A persistent influence of supernovae on biodiversity over the Phanerozoic. [PDF]

Ecol Evol, 2023
It shows the correlation between diversity and supernovae frequency. Abstract It is an open question what has constrained macroevolutionary changes in marine animal diversity on the time scale of the Phanerozoic. Here, we will show that supernovae appear to have significantly influenced the biodiversity of life.

Estimating Ejecta Masses of Stripped-envelope Supernovae Using Late-time Light Curves

The Astrophysical Journal, 2023
Stripped-envelope supernovae (SESNe) are a subclass of core-collapse supernovae that are deficient in hydrogen (SN IIb, SN Ib) and possibly helium (SN Ic) in their spectra.

The Iron Yield of Core-collapse Supernovae

The Astrophysical Journal, 2023
We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their ^56 Ni masses from the luminosity in their radioactive tails ( ${M}_{\mathrm{Ni}}^{\mathrm{tail}}$ ) and/or in their maximum light, and the mean ^56 ...

SN 2022jli: A Type Ic Supernova with Periodic Modulation of Its Light Curve and an Unusually Long Rise

The Astrophysical Journal Letters, 2023
We present multiwavelength photometry and spectroscopy of SN 2022jli, an unprecedented Type Ic supernova discovered in the galaxy NGC 157 at a distance of ≈ 23 Mpc. The multiband light curves reveal many remarkable characteristics. Peaking at a magnitude

Inferring the Progenitor Mass–Kinetic Energy Relation of Stripped-envelope Core-collapse Supernovae from Nebular Spectroscopy

The Astrophysical Journal, 2023
The relation between the progenitor mass and the kinetic energy of the explosion is a key toward revealing the explosion mechanism of stripped-envelope core-collapse supernovae (SESNe).

Type Ic core-collapse supernova explosions evolved from very massive stars [PDF]

, 2013
We investigate the possibility of a super-luminous Type Ic core-collapse supernovae producing a large amount of 56Ni. Very massive stars with a main-sequence mass larger than 100 Msun and a metallicity 0.001 < Z < 0.004 are expected to explode as super ...
