Scientific paper

The KELT project photometrically surveys 50% of the sky using two robotic, wide-field, small aperture telescopes, with the primary goal of discovering transiting exoplanets in the range 8 < V < 10. In Arizona, KELT-North has been running for 4 years, and in South Africa KELT-South has been running for 1.5 years. We have implemented a variant on the ISIS difference imaging pipeline, and are achieving the < 1% photometric precision that allows us to search for transiting planets. The data are being used to create catalogs of variable stars, identify EBs for testing stellar astrophysics, and acquire lightcurves of inner solar system comets. We describe our methods for selecting promising transiting planet candidates, and present some early results from radial velocity and photometric vetting of candidates from KELT-N.
KELT-South is funded by the Vanderbilt Initiative in Data-Intensive Astrophysics (VIDA).
