The Spitzer Space Telescope Survey of the Orion A & B Molecular Clouds - Part I: A Census of Dusty Young Stellar Objects and a Study of their Mid-IR Variability
S. T. Megeath, R. Gutermuth, J. Muzerolle +10
We present a survey of the Orion A and B molecular clouds undertaken with the IRAC and MIPS instruments onboard Spitzer. In total, five distinct fields were mapped covering 9 sq. d…
SOFIA/FORCAST and Spitzer/IRAC Imaging of the Ultra Compact H II Region W3(OH) and Associated Protostars in W3
Lea Hirsch, Joseph D. Adams, Terry L. Herter +8
We present infrared observations of the ultra-compact H II region W3(OH) made by the FORCAST instrument aboard SOFIA and by Spitzer/IRAC. We contribute new wavelength data to the s…
A Spitzer IRAC Measure of the Zodiacal Light
Jessica E. Krick, William J. Glaccum, Sean J. Carey +5
The dominant non-instrumental background source for space-based infrared observatories is the zo- diacal light. We present Spitzer Infrared Array Camera (IRAC) measurements of the…
Thermal Phase Variations of WASP-12b: Defying Predictions
N. B. Cowan, P. Machalek, B. Croll +5
[Abridged] We report Warm Spitzer full-orbit phase observations of WASP-12b at 3.6 and 4.5 micron. We are able to measure the transit depths, eclipse depths, thermal and ellipsoida…
Photoevaporating Proplyd-like objects in Cygnus OB2
Nicholas J. Wright, Jeremy J. Drake, Janet E. Drew +4
We report the discovery of ten proplyd-like objects in the vicinity of the massive OB association Cygnus OB2. They were discovered in IPHAS H-Alpha images and are clearly resolved…
