We obtained late-time optical and near-IR imaging of SN 2008S with the Large Binocular Telescope (LBT). We find that (1) it is again invisible at optical (UBVR) wavelengths to magnitude limits of approximately 25 mag, and (2) while detected in the near-IR (HK) at approximately 20 mag, it is fading rapidly. The near-IR detections in March and May 2010 are consistent with dust emission at a blackbody temperature of T ~ 900 K and a total luminosity of L ~ 40000 Lsun, comparable to the luminosity… Expand

DUSTY EXPLOSIONS FROM DUSTY PROGENITORS: THE PHYSICS OF SN 2008S AND THE 2008 NGC 300-OT
SN 2008S and the 2008 NGC 300-OT were explosive transients of stars self-obscured by very dense, dusty stellar winds. An explosive transient with an unobserved shock breakout luminosity of orderExpand
Luminous blue variable eruptions and related transients: diversity of progenitors and outburst properties
We present new light curves and optical spectra for a number of extragalactic optical transients or 'supernova impostors' related to giant eruptions of luminous blue variables (LBVs), and we provideExpand
LATE-TIME LIGHT CURVES OF TYPE II SUPERNOVAE: PHYSICAL PROPERTIES OF SUPERNOVAE AND THEIR ENVIRONMENT
We present BVRIJHK-band photometry of six core-collapse supernovae, SNe 1999bw, 2002hh, 2003gd, 2004et, 2005cs, and 2006bc, measured at late epochs (>2 yr) based on the Hubble Space Telescope (HST),Expand
EFFECTS OF STELLAR ROTATION ON STAR FORMATION RATES AND COMPARISON TO CORE-COLLAPSE SUPERNOVA RATES
We investigate star formation rate (SFR) calibrations in light of recent developments in the modeling of stellar rotation. Using new published non-rotating and rotating stellar tracks, we study theExpand
The Cosmic Core-collapse Supernova Rate does not match the Massive-Star Formation Rate
We identify a "supernova rate problem": the measured cosmic core-collapse supernova rate is a factor of ~ 2 smaller (with significance ~ 2 sigma) than that predicted from the measured cosmicExpand
The Supernova Impostors
The “supernova impostors” in nearby galaxies mimic the appearance of a true supernova, but rather than a terminal explosion, the impostors appear to be massive stars that have undergone a powerfulExpand
