Far Infrared Prperties of M Dwarfs
Thomas. N. Gautier, G. H. Rieke, John Stansberry +9
We report the mid- and far-infrared properties of nearby M dwarfs. Spitzer/MIPS measurements were obtained for a sample of 62 stars at 24 um, with subsamples of 41 and 20 stars obs…
Near and Mid-IR Photometry of the Pleiades, and a New List of Substellar Candidate Members
John R. Stauffer, Lee W. Hartmann, Giovanni G. Fazio +13
We make use of new near and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously published p…
First Space-Based Microlens Parallax Measurement: Spitzer Observations of OGLE-2005-SMC-001
Subo Dong, A. Udalski, A. Gould +20
We combine Spitzer and ground-based observations to measure the microlens parallax of OGLE-2005-SMC-001, the first such space-based determination since S. Refsdal proposed the idea…
Identification of the Microlens in Event MACHO-LMC-20
Nitya Kallivayalil, Brian M. Patten, Massimo Marengo +3
We report on the identification of the lens responsible for microlensing event MACHO-LMC-20. As part of a \textit{Spitzer}/IRAC program conducting mid-infrared follow-up of the MAC…
Discovery of Two T Dwarf Companions with the Spitzer Space Telescope
K. L. Luhman, B. M. Patten, M. Marengo +12
We report the discovery of T dwarf companions to the nearby stars HN Peg (G0V, 18.4 pc, ~0.3 Gyr) and HD 3651 (K0V, 11.1 pc, ~7 Gyr). During an ongoing survey of 5'x5' fields surro…
The effects of cosmic rays and solar flares on the IRAC detectors: the first two years of in-flight operation
Joseph L. Hora, Brian M. Patten, Giovanni G. Fazio +1
The Infrared Array Camera (IRAC) is a four-channel camera on the Spitzer Space Telescope, one of three focal plane science instruments. IRAC uses two pairs of 256x256 pixel InSb an…
