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…
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}.…

Near-Infrared Photometry of Blazars
C. Chapuis, S. Corbel, P. Durouchoux +2
Two days of observations were conducted at the Palomar Observatory during the nights of 25 and 26 February 1997 with the Hale telescope, in order to search for rapid variability in…
Near-infrared photometry of blazars
C. Chapuis, S. Corbel, P. Durouchoux +2
The rapid variability of blazars in almost all wavelengths is now well established. Two days of observations were conducted at the Palomar Observatory during the nights of 25 and 2…
