The KELT project is a transit survey using two robotic, wide-field, small aperture telescopes, with the primary goal of discovering transiting exoplanets of bright (8 < V < 11) stars. Transiting planets around bright stars are accessible to intensive followup observations at extremely high signal-to-noise, and are the best individual laboratories for studying planet atmospheres and compositions. Discoveries of new bright-star transits are hence of great scientific value. In Arizona, KELT-North has been running for 5 years, and in South Africa KELT-South has been running for 1.5 years. The KELT pipeline implements a modified version of the ISIS difference imaging software package and achieves the required (< 1% RMS) precision to detect Jupiter-sized transiting planets for the typical host stars in our sample. The data are also being used to create catalogs of variable stars, identify EBs for testing stellar astrophysics, and to acquire lightcurves of inner solar system comets. The KELT team is currently following up transit candidates and the KELT data set has potential value for future exoplanet surveys.
The KELT project has received funding from the Vanderbilt Initiative in Data-intensive Astrophysics (VIDA), NSF PAARE grant AST-0849736, NASA Grant No. NNG04G070G, and from NSF CAREER Grant AST-1056524.
