Title: New Dust Production in V838 Monocerotis
Abstract:
The eruptive variable V838 Monocerotis experienced three consecutive, massive
photometric eruptions in 2002 and subsequently developed a magnificent light
echo. Intensive monitoring by ground- and space-based observatories have
traced the dramatic evolution of the object since its eruptions. Recent
Gemini Michelle mid-IR photometric observations revealed the first clear
evidence that new circumstellar dust is condensing from the 2002 outburst
material (Wisniewski et al 2008). We request 1.67 hours of Gemini 2009A time
to a) trace the evolution of this dust production event; and b) determine the
chemical make-up of this newly formed dust. This proposal represents a
continuation of our 2008B director's discretionary program, which is
currently being executed in the Gemini queue.
