Debris disks around Sun-like stars
D. E. Trilling, G. Bryden, C. A. Beichman +7
We have observed nearly 200 FGK stars at 24 and 70 microns with the Spitzer Space Telescope. We identify excess infrared emission, including a number of cases where the observed fl…
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds: VII. Ophiuchus Observed with MIPS
Deborah L. Padgett, Luisa M. Rebull, Karl R. Stapelfeldt +21
We present maps of 14.4 deg^2 of the Ophiuchus dark clouds observed by the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS). These high quality maps depict b…
Multi-Wavelength Imaging of Young Stellar Object Disks: Toward an Understanding of Disk Structure and Dust Evolution
Alan M. Watson, Karl R. Stapelfeldt, Kenneth Wood +1
We review recent progress in high-resolution imaging of scattered light from disks around young stellar objects. Many new disks have been discovered or imaged in scattered light, a…
First Steps in Direct Imaging of Planetary Systems Like our Own: The Science Potential of 2-m Class Optical Space Telescopes
Karl Stapelfeldt, John Trauger, Weslay Traub +4
We summarize the scientific potential of high contrast optical space imaging for studies of extrasolar planets, debris disks, and planet formation. The unique scientific capabiliti…
A Spitzer Study of the Mass Loss Histories of Three Bipolar Pre-Planetary Nebulae
Tuan Do, Mark Morris, Raghvendra Sahai +1
We present the results of far-infrared imaging of extended regions around three bipolar pre-planetary nebulae, AFGL 2688, OH 231.8+4.2, and IRAS 163423814, at 70 and 160 m wi…
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…
