Reduction Algorithms for the Multiband Imaging Photometer for Spitzer: 6 Months of Flight Data
K. D. Gordon, G. H. Rieke, C. W. Engelbracht +27
The first six months of flight data from the Multiband Imaging Photometer for Spitzer (MIPS) were used to test MIPS reduction algorithms based on extensive preflight laboratory dat…
24 micron Properties of X-ray Selected AGN
J. R. Rigby, G. H. Rieke, R. Maiolino +13
We examine the 24 micron to X-ray color of 157 X-ray--selected AGN as a function of X-ray obscuration and optical classification in the Chandra Deep Field South. The sample consist…
IRAC Colors of Young Stellar Objects
Lori E. Allen, Nuria Calvet, Paola D'Alessio +8
We compare the infrared colors predicted by theoretical models of protostellar envelopes and protoplanetary disks with initial observations of young stellar objects made with the I…
Models of Accretion Disks around Young Stars
Paola D'Alessio, Nuria Calvet, Lee Hartmann +2
We discuss the importance of accretion in calculating disk models for young stellar objects. In particular, we show that a disk inner rim, irradiated by both the star and the accre…
Disk Accretion at 10 Myr: Results from the TW Hydrae Association
James Muzerolle, Lynne Hillenbrand, Nuria Calvet +2
We present an analysis of the accretion properties of the members of the TW Hydrae association. The Halpha emission line profile provides explicit evidence of an active accretion f…
