We present the first light results from the Multi-object APO Radial-Velocity Exoplanet Large-area Survey (MARVELS). MARVELS is part of the on-going Sloan Digital Sky Survey (SDSS) III survey which started in July 2008 and will end in July 2014. The data are taken with a multi-object fixed delay interferometer coupled to a R=11,000 spectrograph capable of acquiring precision radial velocities (3-20 m/s depending on V magnitudes) for 60 objects simultaneously in the 3 degree field of view of the SDSS telescope. MARVELS is to monitor a total of 11,000 V=8-12 relatively bright survey stars over 800 square degrees over the 6 years. The survey stars include about 90% F8 and later type main sequence stars and subgiants, and 10% G and K giants with V=7.6-12. MARVELS will produce the largest statistically well defined sample of giant planets drawn from a large of host stars with a diverse set of masses, compositions, and ages which will be used to study exoplanet diversity and planet formation, migration & dynamical evolution. It will also possibly discover rare planet systems and identify signposts for lower-mass or more distant planets. The first two year survey data will be released to the public in 2011. A new planet in a spectroscopic binary system discovered in the MARVELS pilot program will also be reported.
We would like to thank the W.M. Keck Foundation, Sloan Foundation, NSF, NASA and UF for support.
