The Complete Census of 70-um-Bright Debris Disks within the FEPS (Formation and Evolution of Planetary Systems) Spitzer Legacy Survey of Sun-like Stars
Lynne A. Hillenbrand, John M. Carpenter, Jinyoung Serena Kim +7
(abbreviated) We report detection with the Spitzer Space Telescope of cool dust surrounding solar type stars. The observations were performed as part of the Legacy Science Program,…
Evolution of Mid-IR Excess Around Sun-like Stars: Constraints on Models of Terrestrial Planet Formation
M. R. Meyer, J. M. Carpenter, E. E. Mamajek +11
We report observations from the Spitzer Space Telescope (SST) regarding the frequency of 24 micron excess emission toward sun-like stars. Our unbiased sample is comprised of 309 st…
New determination of the size and bulk density of the binary asteroid 22 Kalliope from observations of mutual eclipses
P. Descamps, F. Marchis, J. Pollock +16
In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual equinoxes. As a consequence, the orbit plane of its small moon, Linus, was aligned closely to the Sun's li…
NICMOS Observations of Shocked H_2 in Orion
Sean W. J. Colgan, A. S. B. Schultz, M. J. Kaufman +2
HST NICMOS narrowband images of the shocked molecular hydrogen emission in OMC-1 are analyzed to reveal new information on the BN/KL outflow. The outstanding morphological feature…
Spitzer IRS Observations of the Galactic Center: Shocked Gas in the Radio Arc Bubble
Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +4
We present Spitzer IRS spectra (R ~600, 10 - 38 micron) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude and spanning plus/minus 0.3 degrees in latit…
The Relationship between the Optical Depth of the 9.7 micron Silicate Absorption Feature and Infrared Differential Extinction in Dense Clouds
J. E. Chiar, K. Ennico, Y. J. Pendleton +8
We have examined the relationship between the optical depth of the 9.7 micron silicate absorption feature (tau_9.7) and the near-infrared color excess, E(J-Ks) in the Serpens, Taur…
