Binary progenitor systems for Type Ic supernovae [PDF]

open access: yesNature 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.

The Iron Yield of Core-collapse Supernovae

open access: yesThe 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 ...

Possible Detection of the Progenitor of the Type II Supernova SN 2023ixf

open access: yesThe Astrophysical Journal Letters, 2023
Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is important to constrain the theory and to justify and design future surveys to ...

The Effects of Thomson Scattering and Chemical Mixing on Early-time Light Curves of Double-peaked Type IIb Supernovae

open access: yesThe Astrophysical Journal, 2023
Previous numerical simulations of double-peaked Type IIb supernova (SN IIb) light curves have demonstrated that the radius and mass of the hydrogen-rich envelope of the progenitor star can significantly influence the brightness and timescale of the early-

Inferencing Progenitor and Explosion Properties of Evolving Core-collapse Supernovae from Zwicky Transient Facility Light Curves

open access: yesThe Astrophysical Journal, 2023
We analyze a sample of 45 Type II supernovae from the Zwicky Transient Facility public survey using a grid of hydrodynamical models in order to assess whether theoretically driven forecasts can intelligently guide follow-up observations supporting all ...

SN 2018gk Revisited: the Photosphere, the Central Engine, and the Putative Dust

open access: yesThe Astrophysical Journal, 2023
We perform a comprehensive study of the physical properties of SN 2018gk, which is a luminous Type IIb supernova (SN). We find that the early-time photospheric velocity varies from a larger value to a smaller one before the photosphere reaches a ...

Circumstellar Medium Interaction in SN 2018lab, A Low-luminosity Type IIP Supernova Observed with TESS

open access: yesThe Astrophysical Journal, 2023
We present photometric and spectroscopic data of SN 2018lab, a low-luminosity Type IIP supernova (LLSN) with a V -band peak luminosity of −15.1 ± 0.1 mag.

JWST Imaging of the Cartwheel Galaxy Reveals Dust Associated with SN 2021afdx

open access: yesThe Astrophysical Journal Letters, 2023
We present near- and mid-infrared (0.9–18 μ m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its Early Release Observations of the Cartwheel Galaxy.

The Dusty Red Supergiant Progenitor and the Local Environment of the Type II SN 2023ixf in M101

open access: yesThe Astrophysical Journal Letters, 2023
As one of the closest supernovae (SNe) in the last decade, SN 2023ixf is an unprecedented target to investigate the progenitor star that exploded. However, there is still significant uncertainty in the reported progenitor properties.
