J/AJ/138/703        Deep MIPS observations of IC 348 nebula  (Currie+, 2009)

Deep MIPS observations of the IC 348 nebula: constraints on the evolutionary state of anemic circumstellar disks and the primordial-to-debris disk transition. Currie T., Kenyon S.J. <Astron. J., 138, 703-726 (2009)> =2009AJ....138..703C
ADC_Keywords: Clusters, open ; Stars, pre-main sequence ; Photometry, infrared ; Photometry, millimetric/submm Keywords: open clusters and associations: individual (IC 348) - planetary systems: formation - planetary systems: protoplanetary disks - stars: pre-main sequence Abstract: We describe new, deep MIPS photometry and new high signal-to-noise optical spectroscopy of the 2.5Myr old IC 348 Nebula. To probe the properties of the IC 348 disk population, we combine these data with previous optical/infrared photometry and spectroscopy to identify stars with gas accretion, to examine their mid-IR colors, and to model their spectral energy distributions. Description: Selected IC 348 stars were observed on 2008 March 1 with the FAST spectrograph on the 1.5m Tillinghast telescope at Fred Lawrence Whipple Observatory. IC 348 was reobserved in five separate epochs with MIPS on 2007 September 23-27 (Observing Keys 22961920, 22962176, 22962432, 22962688, and 22962944; PI: J. Muzerolle). File Summary:
