The last gasp of gas giant planet formation: a Spitzer study of the 5 Myr old cluster NGC 2362. Currie T., Lada C.J., Plavchan P., Robitaille T.P., Irwin J., Kenyon S.J. <Astrophys. J., 698, 1-27 (2009)> =2009ApJ...698....1C
ADC_Keywords: Clusters, open ; Photometry, infrared ; Photometry, VRI ; Stars, pre-main sequence Keywords: circumstellar matter - open clusters and associations (individual: NGC 2362) - planetary systems: formation - planetary systems: protoplanetary disks - stars: pre-main sequence Abstract: Expanding upon the Infrared Array Camera (IRAC) survey from Dahm & Hillenbrand (2007, Cat. J/AJ/133/2072), we describe Spitzer IRAC and Multiband Imaging Photometer for Spitzer observations of the populous, 5Myr old open cluster NGC 2362. We analyze the mid-IR colors of cluster members and compared their spectral energy distributions (SEDs) to star+circumstellar disk models to constrain the disk morphologies and evolutionary states. Combining our data with other Spitzer surveys, we investigate the evolution of debris disks around high/intermediate-mass stars and investigate timescales for giant planet formation. Description: NGC 2362 was observed with the IRAC on 2004 March 3 as a part of the Guaranteed Time Observations (GTO) program (Program ID 37). IRAC data cover an area of ∼0.3deg2 centered near RAJ2000∼07h19m00s, DEJ2000~-24°27'00". NGC 2362 was imaged with the MIPS on 2004 March 17 also as a part of the GTO program (ID 58). MIPS data cover ∼0.5deg2 on the sky with boundaries of RAJ2000∼07h17m45s to 07h20m00s and DEJ2000~-25°26'00" to -24°33'00". File Summary:
