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…
On the Nature of the Dust in the Debris Disk Around HD69830
C. M. Lisse, C. A. Beichman, G. Bryden +1
We have used the infrared mineralogical model derived from the Spitzer IRS observations of the Deep Impact experiment to study the nature of the dust in the debris found around the…
Transience of hot dust around sun-like stars
M. C. Wyatt, R. Smith, J. S. Greaves +3
There is currently debate over whether the dust content of planetary systems is stochastically regenerated or originates in planetesimal belts evolving in steady state. In this pap…
Images of Vega Dust Ring at 350 and 450 microns: New Clues to the Trapping of Multiple-Sized Dust Particles in Planetary Resonances
K. A. Marsh, C. D. Dowell, T. Velusamy +2
We have used the SHARC II camera at Caltech Submillimeter Observatory to make 350 and 450 micron images of the Vega dust disk at spatial resolutions (FWHM) of 9.7" and 11.1", respe…
Spitzer/MIPS Limits on Asteroidal Dust in the Pulsar Planetary System PSR B1257+1
G. Bryden, C. A. Beichman, G. H. Rieke +5
With the MIPS camera on Spitzer, we have searched for far-infrared emission from dust in the planetary system orbiting pulsar PSR 1257+12. With accuracies of 0.05 mJy at 24 um and…
Comparative Planetology and the Search for Life Beyond the Solar System
Charles A. Beichman, Malcolm Fridlund, Wesley A. Traub +3
The study of planets beyond the solar system and the search for other habitable planets and life is just beginning. Ground-based (radial velocity and transits) and space-based surv…
IRS Spectra of Solar-Type Stars: A Search for Asteroid Belt Analogs
C. A. Beichman, A. Tanner, G. Bryden +6
We report the results of a spectroscopic search for debris disks surrounding 41 nearby solar type stars, including 8 planet-bearing stars, using the {\it Spitzer Space Telescope}.…
