A luminous optical transient (OT) that appeared in NGC 300 in early 2008 had a maximum brightness, M_V ~ -12 to -13, intermediate between classical novae and supernovae. We present ground-based photometric and spectroscopic monitoring and adaptive-optics imaging of the OT, as well as pre- and post-outburst space-based imaging with HST and Spitzer. The optical spectrum at maximum showed an F-type supergiant photosphere with superposed emission lines of hydrogen, Ca II, and [Ca II], similar to… Expand

An unusually brilliant transient in the galaxy M85
TLDR
The discovery of an optical transient in the outskirts of the lenticular galaxy Messier 85 in the Virgo cluster is reported, distinctly brighter than novae, but fainter than type Ia supernovae (which is expected in a population of old stars in lenticular galaxies). Expand
Discovery of the Dust-Enshrouded Progenitor of SN 2008S with Spitzer
We report the discovery of the progenitor of the recent Type IIn SN 2008S in the nearby galaxy NGC 6946. Surprisingly, it was not found in deep, preexplosion optical images of its host galaxy takenExpand
SN 2008S: A COOL SUPER-EDDINGTON WIND IN A SUPERNOVA IMPOSTOR

An energetic stellar outburst accompanied by circumstellar light echoes
TLDR
High-resolution imaging and polarimetry of light echoes indicate that V838 Mon represents a hitherto unknown type of stellar outburst, for which the authors have no completely satisfactory physical explanation. Expand
