Late-time Light Curves of Type II Supernovae: Physical Properties of SNe and Their Environment
Masaaki Otsuka, Margaret Meixner, Nino Panagia +9
We present BVRIJHK band photometry of 6 core-collapse supernovae, SNe 1999bw, 2002hh, 2003gd, 2004et, 2005cs, and 2006bc measured at late epochs (>2 yrs) based on Hubble Space Tele…
The effects of dust on the optical and infrared evolution of SN 2004et
J. Fabbri, M. Otsuka, M. J. Barlow +8
We present an analysis of multi-epoch observations of the Type II-P supernova SN 2004et. New and archival optical spectra of SN 2004et are used to study the evolution of the Halpha…
The Dust Properties of Two Hot R Coronae Borealis Stars and a Wolf-Rayet Central Star of a Planetary Nebula: in Search of a Possible Link
Geoffrey C. Clayton, O. De Marco, B. A. Whitney +14
We present new Spitzer/IRS spectra of two hot R Coronae Borealis (RCB) stars, one in the Galaxy,V348 Sgr, and one lying in the LMC, HV 2671. These two objects may constitute a link…
Evidence for Pre-Existing Dust in the Bright Type IIn SN 2010jl
J. E. Andrews, Geoffrey C. Clayton, R. Wesson +11
SN 2010jl was an extremely bright, Type IIn SNe which showed a significant IR excess no later than 90 days after explosion. We have obtained Spitzer 3.6 and 4.5 \mum and JHK observ…
VLTI observations of the dust geometry around R Coronae Borealis stars
S. N. Bright, O. Chesneau, G. C. Clayton +4
We are investigating the formation and evolution of dust around the hydrogen-deficient supergiants known as R Coronae Borealis (RCB) stars. We aim to determine the connection betwe…
Photometric and Spectroscopic Evolution of the Type IIP SN 2007it to Day 944
J. E. Andrews, B. E. K Sugerman, Geoffrey Clayton +9
SN 2007it is a bright, Type IIP supernova which shows indications of both pre-existing and newly formed dust. The visible photometry shows a bright late-time luminosity, powered by…
