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…
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…
When Do Planets Form? A Search for Extra-solar Planets Around Metal-Poor Stars
A. Sozzetti, D. W. Latham, G. Torres +4
We present preliminary results from our spectroscopic search for planets within 1 AU of metal-poor field dwarfs using NASA time with HIRES on Keck I. The core accretion model of ga…
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…
An interferometric-spectroscopic orbit for the binary HD 195987: Testing models of stellar evolution for metal-poor stars
Guillermo Torres, Andrew F. Boden, David W. Latham +2
We report spectroscopic and interferometric observations of the moderately metal-poor double-lined binary system HD 195987, with an orbital period of 57.3 days. By combining our ra…
