V838 Monocerotis: A Geometric Distance from Hubble Space Telescope Polarimetric Imaging of its Light Echo
William B. Sparks, Howard E. Bond, Misty Cracraft +10
Following the outburst of the unusual variable star V838 Monocerotis in 2002, a spectacular light echo appeared. A light echo provides the possibility of direct geometric distance…
Dust yields in clumpy SN shells: SN 1987A revisited
B. Ercolano, M. J. Barlow, B. E. K. Sugerman
We present a study of the effects of clumping on the emergent spectral energy distribution (SED) from dusty supernova (SN) shells illuminated by a diffuse radiation source distribu…
Discovery of a Light Echo from Supernova 2003gd
Ben E. K. Sugerman
Archival HST/ACS data reveal details of a light echo around SN 2003gd in the galaxy M74, only the fifth supernova around which resolved echoes have been reported. An echo is detect…
Detection of a massive dust shell around the Type II supernova SN 2002hh
M. J. Barlow, B. E. K. Sugerman, J. Fabbri +11
Dust emission from the Type II supernova SN 2002hh in NGC 6946 has been detected at mid-infrared wavelengths by the Spitzer Space Telescope from 590 to 758 days after outburst and…
The Three-Dimensional Circumstellar Environment of SN 1987A
Ben E. K. Sugerman, Arlin P. S. Crotts, William E. Kunkel +2
We present the detailed construction and analysis of the most complete map to date of the circumstellar environment around SN 1987A, using ground and space-based imaging from the p…
A New View of the Circumstellar Environment of SN 1987A
Ben E. K. Sugerman, Arlin P. S. Crotts, William E. Kunkel +2
We summarize the analysis of a uniform set of both previously-known and newly-discovered scattered-light echoes, detected within 30" of SN 1987A in ten years of optical imaging, an…
