The radial distribution of core-collapse supernovae in spiral host galaxies
A. A. Hakobyan, G. A. Mamon, A. R. Petrosian +2
With the goal of providing constraints on the nature of the progenitors of core-collapse supernovae, we compare their radial distribution within their spiral host galaxies with the…
VLT Spectropolarimetry of the optical transient in NGC300. Evidence for asymmetry in the circumstellar dust
F. Patat, J. R. Maund, S. Benetti +4
AIMS: The main goal of this work is to study possible signs of asymmetry in the bright optical transient in NGC300, with the aim of getting independent information on the explosion…
SN 1999ga: a low-luminosity linear type II supernova?
A. Pastorello, R. M. Crockett, R. Martin +11
Type II-linear supernovae are thought to arise from progenitors that have lost most of their H envelope by the time of the explosion, and they are poorly understood because they ar…
Five supernova survey galaxies in the southern hemisphere. I. Optical and near-infrared database
A. A. Hakobyan, A. R. Petrosian, G. A. Mamon +8
The determination of the supernova (SN) rate is based not only on the number of detected events, but also on the properties of the parent galaxy population. This is the first paper…
SN 2008S: an electron capture SN from a super-AGB progenitor?
M. T. Botticella, A. Pastorello, S. J. Smartt +31
We present comprehensive photometric and spectroscopic observations of the faint transient SN 2008S discovered in NGC 6946. SN 2008S exhibited slow photometric evolution and almost…
