Detection of Thermal Emission from an Extrasolar Planet
David Charbonneau, Lori E. Allen, S. Thomas Megeath +8
We present Spitzer Space Telescope infrared photometric time series of the transiting extrasolar planet system TrES-1. The data span a predicted time of secondary eclipse, correspo…
The Challenge of Wide-Field Transit Surveys: The Case of GSC 01944-02289
Georgi Mandushev, Guillermo Torres, David W. Latham +7
Wide-field searches for transiting extra-solar giant planets face the difficult challenge of separating true transit events from the numerous false positives caused by isolated or…
TrES-1: The Transiting Planet of a Bright K0V Star
Roi Alonso, Timothy M. Brown, Guillermo Torres +9
We report the detection of a transiting Jupiter-sized planet orbiting a relatively bright (V=11.79) K0V star. We detected the transit light-curve signature in the course of the TrE…
Combining Astrometry and Spectroscopy
Guillermo Torres
Orbital solutions for binary or multiple stellar systems that combine astrometry (e.g., position angles and angular separations) with spectroscopy (radial velocities) have importan…
Spatially Resolved STIS Spectroscopy of Betelgeuse's Outer Atmosphere
A. Lobel, J. Aufdenberg, A. K. Dupree +3
We present spatially resolved spectra observed with HST-STIS of the upper chromosphere and dust envelope of Alpha Orionis (M2 Iab). In the fall of 2002 a set of five high-resolutio…
The Millennium Outburst of the Cool Hypergiant Rho Cassiopeiae: Spectroscopy and Modeling
A. Lobel, A. K. Dupree, R. P. Stefanik +7
Between 2000 June and September an exceptional variability phase occurred in the peculiar F-type hypergiant Rho Cas, when the V-brightness dimmed by at least a full magnitude. The…
