Debris disks in main sequence binary systems
D. E. Trilling, J. A. Stansberry, K. R. Stapelfeldt +8
We observed 69 A3-F8 main sequence binary star systems using the Multiband Imaging Photometer for Spitzer onboard the Spitzer Space Telescope. We find emission significantly in exc…
New Debris Disks Around Nearby Main Sequence Stars: Impact on The Direct Detection of Planets
C. Beichman, G. Bryden, K. Stapelfeldt
Using the MIPS instrument on the Spitzer telescope, we have searched for infrared excesses around a sample of 82 stars, mostly F, G, and K main-sequence field stars, along with a s…
Strong dusty bursts of star formation in galaxies falling into the cluster RXJ0152.7-1357
D. Marcillac, J. Rigby, G. Rieke +1
We have observed the cluster RX J0152.7-1357 (z0.83) at 24m with the Multiband Imaging Photometer for Spitzer (MIPS). We detected twenty-two sources associated with spectr…
High spatial resolution T-ReCS mid-infrared imaging of Luminous Infrared Galaxies
A. Alonso-Herrero, L. Colina, C. Packham +4
We present diffraction-limited (FWHM ~ 0.3arcsec) Gemini/T-ReCS mid-infrared (MIR: N-band or narrow-band at 8.7micron) imaging of four Luminous Infrared Galaxies (LIRGs) drawn from…
A Large Mass of H2 in the Brightest Cluster Galaxy in Zwicky 3146
E. Egami, G. H. Rieke, D. Fadda +1
We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (L_{IR}=4e11 L_sun) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Z3146 (z=0.29). The spect…
Debris Disk Evolution Around A Stars
K. Y. L. Su, G. H. Rieke, J. A. Stansberry +8
We report 24 and/or 70 um measurements of ~160 A-type main-sequence stars using the Multiband Imaging Photometer for Spitzer (MIPS). Their ages range from 5 to 850 Myr based on est…
