Boron Synthesis in Type Ic Supernovae [PDF]

The Astrophysical Journal, 2010
We investigate the neutrino-process in an energetic Type Ic supernova (SN Ic) and resultant productions of the light elements including boron and its stable isotopes.

Hydrogen in Type Ic Supernovae? [PDF]

Publications of the Astronomical Society of the Pacific, 2006
By definition, a Type Ic supernova (SN Ic) does not have conspicuous lines of hydrogen or helium in its optical spectrum. SNe Ic usually are modelled in terms of the gravitational collapse of bare carbon-oxygen cores. We consider the possibility that the

Broad-line type Ic Supernova SN 2014ad [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
We present optical and ultraviolet photometry, and low resolution optical spectroscopy of the broad-line type Ic supernova SN 2014ad in the galaxy PGC 37625 (Mrk 1309), covering the evolution of the supernova during $-$5 to +87 d with respect to the date

Studying the Power Sources behind Type Ic Supernovae

The Astrophysical Journal
Astrophysical transients can be powered by a broad range of energy sources, including shock heating (internal and external shocks), decay of radioactive isotopes, and long-lived central engines (magnetar and fallback).

The Broad-lined Type Ic SN 2003jd [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
The results of a world-wide coordinated observational campaign on the broad-lined Type Ic SN 2003jd are presented. In total, 74 photometric data points and 26 spectra were collected using 11 different telescopes.

Testing Cosmological Models with Type Ic Super Luminous Supernovae [PDF]

The Astronomical Journal, 2015
The use of type Ic Super Luminous Supernovae (SLSN Ic) to examine the cosmological expansion introduces a new standard ruler with which to test theoretical models.

High rate for Type IC supernovae [PDF]

The Astrophysical Journal, 1992
Using an automated telescope we have detected 20 supernovae in carefully documented observations of nearby galaxies. The supernova rates for late spiral (Sbc, Sc, Scd, and Sd) galaxies, normalized to a blue luminosity of 10{sup 10} L{sub Bsun}, are 0.4 h{sup 2}, 1.6 h{sup 2}, and 1.1 h{sup 2} per 100 years for SNe type la, Ic, and II. The rate for type

Type Ic supernova of a 22 M⊙ progenitor [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Type Ic supernovae (SNe Ic) are a sub-class of core-collapse SNe that exhibit no helium or hydrogen lines in their spectra. Their progenitors are thought to be bare carbon–oxygen cores formed during the evolution of massive stars that are stripped of their hydrogen and helium envelopes sometime before collapse.

SN 2004aw: confirming diversity of Type Ic supernovae [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
Optical and near-infrared observations of the Type Ic supernova (SN) 2004aw are presented, obtained from day -3 to day +413 with respect to the B-band maximum. The photometric evolution is characterised by a comparatively slow post-maximum decline of the light curves.
