The Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS) is a ground-based Doppler survey of 11,000 of the brightest stars.[1] The project will use the SDSS telescope and new multi-object Doppler instruments to monitor radial velocities.[1] It is one of four astronomical surveys conducted by SDSS-III, part of the Sloan Digital Sky Survey (SDSS).
The main goal of the project is to generate a large-scale, statistically well-defined sample of giant planets. It will search for gaseous planets that have orbital periods ranging from hours to 2 years, and are between 0.5 and 10 Jupiter masses. A total of 11,000 stars will be analyzed with 25-35 observations per star over an 18 month period. It is expected to detect between 150 and 200 new exoplanets, and will be able to study rare systems, such as planets with extreme eccentricity, and objects in the "brown dwarf desert".[1][2]
The collected data will be used as a statistical sample for the theoretical comparison and discovery of rare systems.[3]
The project started in the fall of 2008, and will continue until spring 2014.[1][4]
