Title: Radial-Velocity Confirmation for Two Promising Exoplanet Candidates in Praesepe
Abstract: Transiting exoplanets orbiting bright stars are the most scientifically valuable extrasolar planets. In the past two years wide- angle surveys have begun to yield confirmed transiting planets. Our Kilodegree Extremely Little Telescope (KELT) project has found four planetary transit candidates in the project's commissioning observations of the Praesepe cluster. All four targets have been observed with low- resolution spectroscopy, which identified two of the candidates as astrophysical false positives (different types of stellar eclipsing binaries). To establish the planetary nature of the remaining two candidates, we require high-resolution spectroscopy capable of extremely precise radial velocity measurements. The Exoplanet Tracker (ET) is well-equipped to perform the necessary follow-up observations of these candidates. We propose to use ET to confirm that these two KELT candidates are indeed transiting extrasolar planets and to establish preliminary orbital solutions for the planets.
