Young Stars in the Time Domain: A Cool Stars 16 Splinter Summary
Kevin R. Covey, Peter Plavchan, Fabienne Bastien +6
Variability is a defining characteristic of young stellar systems, and optical variability has been heavily studied to select and characterize the photospheric properties of young…
The Application of Cloud Computing to Astronomy: A Study of Cost and Performance
G. Bruce Berriman, Ewa Deelman, Gideon Juve +2
Cloud computing is a powerful new technology that is widely used in the business world. Recently, we have been investigating the benefits it offers to scientific computing. We have…
Characterizing the Variability of Stars with Early-Release Kepler Data
David R. Ciardi, Kaspar von Braun, Geoff Bryden +6
We present a variability analysis of the early-release first quarter of data publicly released by the Kepler project. Using the stellar parameters from the Kepler Input Catalog, we…
Deep Near-Infrared Imaging of the rho Oph Cloud Core: Clues to the Origin of the Lowest-Mass Brown Dwarfs
Kenneth A. Marsh, Peter Plavchan, J. Davy Kirkpatrick +3
A search for young substellar objects in the rho Oph cloud core region has been made using the deep-integration Combined Calibration Scan images of the 2MASS extended mission in J,…
Accurate Coordinates and 2MASS Cross-IDs for (Almost) All Gliese Catalog Stars
John Stauffer, Angelle M. Tanner, Geoffrey Bryden +10
We provide precise J2000, epoch 2000 coordinates and cross-identifications to sources in the 2MASS point source catalog for nearly all stars in the Gliese, Gliese and Jahreiss, and…
Debris Disks around Solar-Type Stars: Observations of the Pleiades with Spitzer Space Telescope
J. M. Sierchio, G. H. Rieke, K. Y. L. Su +3
We present Spitzer MIPS observations at 24 um of 37 solar-type stars in the Pleiades and combine them with previous observations to obtain a sample of 71 stars. We report that 23 s…
