The death of massive stars – I. Observational constraints on the progenitors of Type II-P supernovae
- S. Smartt, J. Eldridge, R. Crockett, J. R. M. Q. U. B. IoA, Cambridge Dark Cosmology Centre, Copenhagen
- Physics
- 2 September 2008
The progenitors of many type II core-collapse supernovae have now been identified directly on pre-discovery imaging. Here we present an extensive search for the progenitors of type Ibc supernovae in…
SN 2008S: An electron-capture SN from a super-AGB progenitor?
- M. Botticella, A. Pastorello, I. Volkov
- Physics
- 6 March 2009
We present comprehensive photometric and spectroscopic observations of the faint transient SN 2008S discovered in the nearby galaxy NGC 6946. SN 2008S exhibited slow photometric evolution and almost…
The Type IIb SN 2008ax: spectral and light curve evolution
- A. Pastorello, M. Kasliwal, W. Wiethoff
- Physics
- 13 May 2008
We present spectroscopy and photometry of the He-rich supernova (SN) 2008ax. The early-time spectra show prominent P-Cygni H lines, which decrease with time and disappear completely about 2 months…
A deeper search for the progenitor of the Type Ic Supernova 2002ap
- R. Crockett, S. Smartt, I. Skillen
- Physics, Geology
- 4 June 2007
Images of the site of the Type Ic Supernova 2002ap taken before explosion were analysed previously by Smartt et al. (2002). We have uncovered new unpublished, archival pre-explosion images from the…
Massive stars exploding in a He-rich circumstellar medium – II. The transitional case of SN 2005la
- A. Pastorello, R. Quimby, D. Young
- Physics
- 15 January 2008
We present photometric and spectroscopic data of the peculiar SN 20051a, an object which shows an optical light curve with some luminosity fluctuations and spectra with comparably strong narrow…
The Birth Place of the Type Ic Supernova 2007gr
- R. Crockett, J. Maund, C. Benn
- Physics
- 14 September 2007
We report our attempts to locate the progenitor of the peculiar Type Ic SN 2007gr in Hubble Space Telescope (HST) preexplosion images of the host galaxy, NGC 1058. Aligning adaptive optics…
SN 2004A: Another Type II-P Supernova with a Red Supergiant Progenitor
We present a monitoring study of SN 2004A and probable discovery of a progenitor star in pre-explosion Hubble Space Telescope (HST) images. The photometric and spectroscopic monitoring of SN 2004A…
VLT Detection of a Red Supergiant Progenitor of the Type II-P Supernova 2008bk
- S. Mattila, S. Smartt, J. Eldridge, J. Maund, R. Crockett, I. J. Danziger
- Physics
- 1 September 2008
We report the identification of a source coincident with the position of the nearby Type II-P supernova (SN) 2008bk in high-quality optical and near-infrared preexplosion images from the ESO Very…
SN 2009md: another faint supernova from a low-mass progenitor
- M. Fraser, M. Ergon, M. Turatto
- Physics
- 30 November 2010
We present adaptive optics imaging of the core-collapse supernova (SN) 2009md, which we use together with archival Hubble Space Telescope data to identify a coincident progenitor candidate. We find…
The death of massive stars - II. Observational constraints on the progenitors of type Ibc supernovae
- J. Eldridge, M. Fraser, S. Smartt, J. Maund, R. Crockett
- Physics
- 9 January 2013
The progenitors of many Type II core-collapse supernovae (SNe) have now been identified directly on pre-discovery imaging. Here, we present an extensive search for the progenitors of Type Ibc SNe in…
