Searching for Wolf-Rayet Stars in M101

, 2011
Wolf-Rayet (WR) stars are the evolved descendants of massive O-type stars and are considered to be progenitor candidates for Type Ib/c core-collapse supernovae (SNe).

Multiphase Shock Cooling Emission in Ultrastripped Supernovae

The Astrophysical Journal
Ultrastripped and Type Ibn supernovae (USSNe and SNe Ibn, respectively) are fast-evolving, hydrogen-poor transients that often show signs of interaction with dense circumstellar material (CSM). S. C. Wu & J.

Direct Analysis of Spectra of Type Ib Supernovae [PDF]

The Astrophysical Journal, 2002
Synthetic spectra generated with the parameterized supernova synthetic-spectrum code SYNOW are compared to photospheric-phase spectra of Type Ib supernovae (SNe Ib). Although the synthetic spectra are based on many simplifying approximations, including spherical symmetry, they account well for the observed spectra.

Near-infrared Spectral Properties of Type Ib/Ic Supernova Progenitors and Implications for JWST and NGRST Observations

The Astrophysical Journal
While about 20 type II supernova (SN II) progenitors have been identified using optical data from the Hubble Space Telescope (HST), direct detection of type Ib/Ic supernova (SN Ib/Ic) progenitors remains challenging, due to their faint optical brightness

The nature of Long-GRB host galaxies from chemical abundances

, 2010
Gamma-ray bursts (GRBs) are the most energetic events after the Big Bang and they have been observed up to very high redshift. By means of measures of chemical abundances now available for the galaxies hosting such events,thought to originate from the ...

Spectropolarimetric Evolution Reveals Dual-axis Ejecta in the Atypical Magnetar-powered SN 2012au

The Astrophysical Journal
We present six epochs of optical spectropolarimetric observations of the unique and slow-evolving Type Ib supernova (SN) 2012au, between 0 and 295 day post- R -band maximum.

A White Dwarf Merger Paradigm for Supernovae and Gamma-Ray Bursts

, 2003
Gamma-ray bursts can appear to be a hundred times as luminous as supernovae, but their underlying energy source(s) have remained a mystery. However, there has been evidence for some time now of an association of gamma-ray bursts with supernovae of Type ...

Probing Presupernova Mass Loss in Double-peaked Type Ibc Supernovae from the Zwicky Transient Facility

The Astrophysical Journal
Eruptive mass loss of massive stars prior to supernova (SN) explosion is key to understanding their evolution and end fate. An observational signature of pre-SN mass loss is the detection of an early, short-lived peak prior to the radioactive-powered ...

Probing Shock Breakout and Progenitors of Stripped-Envelope Supernovae through Their Early Radio Emissions

, 2012
We study properties of early radio emission from stripped-envelope supernovae (those of type IIb/Ib/Ic). We suggest there is a sub-class of stripped-envelope supernovae in their radio properties, including optically well-studied type Ic supernovae (SNe ...
