Searching the Next 2000 Stars for Hot Jupiters
N2K Project Overview
Ongoing precise radial velocity surveys of ~2000 stars have discovered over 150 extrasolar planets, including many "Hot Jupiters": massive planets orbiting surprisingly close to their host stars. Fortuitous alignment of the orbital planes has caused three such planets to transit in front of bright host stars, revealing a wealth of information about these planets: density, composition, and even interior structure... Using the now well-established correlation between host stars' heavy element abundance and the frequency of planets, we select high metallicity stars from a pool of 14,000, and distribute them to three observatories: Keck, Subaru and Magellan. Precise radial velocities obtained over three nights at these observatories identify candidate hot jupiters for intense monitoring. Planets then found in small orbits (P < 14 days) have relatively high probability for transit (~10%) and are monitored photometrically at Fairborn Observatory. A full description of our technique can be found in the first paper below.
