Abstract Two years ago, a warm Spitzer survey of sixty-eight SNe IIn identified between the years 1998-2008 discovered 10 events with unreported late-time infrared (IR) excesses, in some cases more than 5 years post-explosion. These data nearly double the database of existing mid-IR observations of SNe IIn and offer important clues regarding the SN circumstellar http://www.abstractsonline.com/Plan /ViewAbstract.aspx?sKey=c6a 7 ... e-61e b3 7 8d 2 e9 5&m Key=%7b2 5 3 69FS 4-5 CBO-46 3 9-BC2 0-B2 02 7 3 090B9A%7 d Page 1 of 3 OASIS 1/6/12 2:38 PM 2000 Florida Ave., NW Suite 400 Washington, DC 20009 The Online Abstract Submission and Invitation System © 1996 - 2012 Coe-Truman Technologies, Inc.
