A MAJOR AND LASTING SCIENTIFIC CONTRIBUTION OF THE PRIME KEPLER MISSION (2009-2013) IS THE SAMPLE OF OVER 4000 PLANET CANDIDATES HAVING ORBITAL PERIODS EXTENDING OUT TO 1 YEAR. THIS DISTRIBUTION ENCODES KEY ASPECTS OF PLANET FORMATION PHYSICS INCLUDING THE GROWTH OF SOLID CORES ACCRETION OF GAS PHOTOEVAPORATION OF GASEOUS ENVELOPES AND ORBITAL MIGRATION. IN THIS PROJECT WE WILL CONSTRUCT A HIGH-PRECISION HIGH-PURITY SAMPLE OF 2600 KEPLER PLANETS SUPPLEMENTING THE KEPLER DATASET WITH OUR KECK SPECTROSCOPY/IMAGING.
