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).
