SN 2020cpg: an energetic link between Type IIb and Ib supernovae [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Stripped-envelope supernovae (SE-SNe) show a wide variety of photometric and spectroscopic properties. This is due to the different potential formation channels and the stripping mechanism that allows for a large diversity within the progenitors outer envelope compositions. Here, the photometric and spectroscopic observations of

A Radio Survey of Type Ib and Ic Supernovae: Searching for Engine‐driven Supernovae [PDF]
The Astrophysical Journal, 2003 The association of gamma-ray bursts (GRBs) and core-collapse supernovae (SNe) of Type Ib and Ic was motivated by the detection of SN 1998bw in the error box of GRB 980425 and the now-secure identification of a SN 1998bw-like event in the cosmological GRB 030329.

Luminous Supernovae: Unveiling a Population Between Superluminous and Normal Core-collapse Supernovae [PDF]
, 2022 Stripped-envelope core-collapse supernovae can be divided into two broad classes: the common Type Ib/c supernovae (SNe Ib/c), powered by the radioactive decay of $^{56}$Ni, and the rare superluminous supernovae (SLSNe), most likely powered by the spin ...

He Abundance of Dense Circumstellar Clumps in the Cassiopeia A Supernova Remnant
The Astrophysical Journal, 2023 We report on the result of He abundance analysis of dense circumstellar clumps in the young supernova remnant Cassiopeia A. These clumps, which are called quasi-sta tionary flocculi (QSFs), are known from previous optical studies to be enriched in He ...

Type Ib/c Supernovae and their Relation to Binary Stars [PDF]
Symposium - International Astronomical Union, 1996 The present understanding of type Ib/c supernovae and their connection to interacting binaries is reviewed. The problems of the classification and the lack of well-observed events exclude direct inference of progenitor characteristics. The absence of hydrogen lines in the observed spectrum, nevertheless, requires restricted evolutionary schemes to ...

Type Ib Supernova 2007uy – a multiwavelegth perspective [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractWe present the results from a comprehensive analysis of a Type Ib supernova (SN) 2007uy in a nearby galaxy NGC 2770 (~30 Mpc), using data from space-based Swift/UVOT, along with ground-based observations at visible, infrared and radio wave bands.

Abundance Tomography of Type Ia Supernovae [PDF]
, 2004 Many uncertainties about the physics of Type Ia Supernovae have been revealed in the recent past, and numerous pieces are puzzled together to achieve a complete description of the phenomenon of thermonuclear explosions in the sky. However, very important

SPY - the ESO Supernovae type Ia Progenitor survey [PDF]
, 2003 Supernovae (SNe) mark the violent termination of a star’s life in an explosion. They are classified according to their light curve as type I or II, with the type I SNe producing very similar light curves, while the SNe type II are more diverse ...
