The possible detection of a binary companion to a Type Ibn supernova progenitor
J. R. Maund, A. Pastorello, S. Mattila +2
We present late-time observations of the site of the Type Ibn supernova (SN) 2006jc acquired with the Hubble Space Telescope Advanced Camera for Surveys. A faint blue source is rec…
Dead or Alive? Long-term evolution of SN 2015bh (SNhunt275)
N. Elias-Rosa, A. Pastorello, S. Benetti +37
Supernova (SN) 2015bh (or SNhunt275) was discovered in NGC 2770 on 2015 February with an absolute magnitude of Mr ~ -13.4 mag, and was initially classified as a SN impostor. Here w…
Interacting supernovae and supernova impostors. SN 2007sv: the major eruption of a massive star in UGC 5979
L. Tartaglia, A. Pastorello, S. Taubenberger +15
We report the results of the photometric and spectroscopic monitoring campaign of the transient SN 2007sv. The observables are similar to those of type IIn supernovae, a well-known…
Detection of an outburst one year prior to the explosion of SN 2011ht
M. Fraser, M. Magee, R. Kotak +18
Using imaging from the Pan-STARRS1 survey, we identify a precursor outburst at epochs 287 and 170 days prior to the reported explosion of the purported Type IIn supernova (SN) 2011…
SN 2009E: a faint clone of SN 1987A
A. Pastorello, M. L. Pumo, H. Navasardyan +26
In this paper we investigate the properties of SN 2009E, which exploded in a relatively nearby spiral galaxy (NGC 4141) and that is probably the faintest 1987A-like supernova disco…
A giant outburst two years before the core-collapse of a massive star
A. Pastorello, S. J. Smartt, S. Mattila +32
The death of massive stars produces a variety of supernovae, which are linked to the structure of the exploding stars. The detection of several precursor stars of Type II supernova…
