Optical Images of an Exosolar Planet 25 Light Years from Earth
Paul Kalas, James R. Graham, Eugene Chiang +6
Fomalhaut is a bright star 7.7 parsecs (25 light years) from Earth that harbors a belt of cold dust with a structure consistent with gravitational sculpting by an orbiting planet.…
The Spitzer c2d Legacy Results: Star Formation Rates and Efficiencies; Evolution and Lifetimes
Neal J. Evans, Michael M. Dunham, Jes K. Jørgensen +15
(Abridged) The c2d Spitzer Legacy project obtained images and photometry with both IRAC and MIPS instruments for five large, nearby molecular clouds. This paper combines informatio…
Epsilon Eridani's Planetary Debris Disk: Structure and Dynamics based on Spitzer and CSO Observations
D. Backman, M. Marengo, K. Stapelfeldt +9
Spitzer and Caltech Submillimeter Observatory (CSO) images and spectrophotometry of epsilon Eridani at wavelengths from 3.5 to 350 um reveal new details of its bright debris disk.…
A Distance-Limited Imaging Survey of Sub-Stellar Companions to Solar Neighborhood Stars
Joseph C. Carson, Kyle D. Hiner, Gregorio G. Villar +3
We report techniques and results of a Palomar 200-inch (5 m) adaptive optics imaging survey of sub-stellar companions to solar-type stars. The survey consists of Ks coronagraphic o…
A Multi-Epoch HST Study of the Herbig-Haro Flow from XZ Tauri
John E. Krist, Karl. R. Stapelfeldt, J. Jeff Hester +3
We present nine epochs of Hubble Space Telescope optical imaging of the bipolar outflow from the pre-main sequence binary XZ Tauri. Our data monitors the system from 1995-2005 and…
The Photometric Variability of HH 30
Alan M. Watson, María Carolina Durán-Rojas, Karl R. Stapelfeldt
HH 30 is an edge-on disk around a young stellar object. Previous imaging with the Hubble Space Telescope has show morphological variability that is possibly related to the rotation…
