Atomic gas properties at the positions of Type Ia, II, and Ib/c supernovae

open access: yesAstronomy & Astrophysics
Context. Understanding which stars explode as which type of supernova (SN) is crucial to measure their contribution to the metal production and feedback halting star formation.

Late Jets, Early Sparks: Illuminating the Premaximum Bumps in Superluminous Supernovae

open access: yesThe Astrophysical Journal Letters
Superluminous supernovae (SLSNe) radiate ≳10–100 times more energy than ordinary stellar explosions, implicating a novel power source behind these enigmatic events.

Bridging the gap between SLSNe and SE-SNe

open access: yesAstronomy & Astrophysics
The Type I super-luminous supernova SN 2024jlc (ZTF24aapadbb) exploded on 25 May 2024 at z = 0.039. This was the closest supernova of this class discovered in recent years and one of the closest ever.

Evolutionary Models for Type Ib/c Supernova Progenitors [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2015
AbstractSNe Ib/c mark the deaths of hydrogen-deficient massive stars. The evolutionary scenarios for SNe Ib/c progenitors involve many important physical processes including mass loss by winds and its metallicity dependence, stellar rotation, and binary interactions. This makes SNe Ib/c an excellent test bed for stellar evolution theory.

Constraints on Type Ib/c Supernovae and Gamma-Ray Burst Progenitors

open access: yes, 2015
Although there is strong support for the collapsar engine as the power source of long-duration gamma-ray bursts (GRBs), we still do not definitively know the progenitor of these explosions.

Multifilter UV to Near-infrared Data-driven Light-curve Templates for Stripped-envelope Supernovae

open access: yesThe Astrophysical Journal Supplement Series
While the spectroscopic classification scheme for stripped-envelope supernovae (SESNe) is clear, and we know that they originate from massive stars that lost some or all of their envelopes of hydrogen and helium, the photometric evolution of classes ...

Fast radio bursts as standard candles for cosmology

open access: yesPhysics Letters B
Recently, fast radio bursts (FRBs) have become a thriving field in astronomy and cosmology. Due to their extragalactic and cosmological origin, they are useful to study the cosmic expansion and the intergalactic medium (IGM).

Type Ibn supernovae from ultra-stripped supernova progenitors

open access: yes
<jats:title>Abstract</jats:title> <jats:p>Ultra-stripped supernovae are core-collapse supernovae from progenitors that lose a significant fraction of mass because of the binary interactions with their compact companion stars.

SN 2023zaw: An Ultrastripped, Nickel-poor Supernova from a Low-mass Progenitor

open access: yesThe Astrophysical Journal Letters
We present SN 2023zaw—a subluminous ( M _r = −16.7 mag) and rapidly evolving supernova ( t _1/2, _r = 4.9 days), with the lowest nickel mass (≈0.002 M _⊙ ) measured among all stripped-envelope supernovae discovered to date.
