cds-question@unistra.frg-starsradial-velocitymultiple-starssolar-system-planetsWe present precision radial velocity data that reveal a multiple exoplanet system orbiting the bright nearby G5V star 61 Virginis. Our 4.6 years of combined Keck/HIRES and Anglo-Australian Telescope precision radial velocities indicate the hitherto unknown presence of at least three planets orbiting this well-studied star. These planets are all on low-eccentricity orbits with periods of 4.2, 38.0, and 124.0 days, and projected masses (Msini) of 5.1, 18.2, and 24.0M_{earth}_, respectively. Test integrations of systems consistent with the radial velocity data suggest that the configuration is dynamically stable.2010ApJ...708.1366Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/708/1366CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/eso : ESO Science Archive Catalog (ESO, 2012)B/mk : Catalogue of Stellar Spectral Classifications (Skiff, 2010)B/cfht : Log of CFHT Exposures (CADC, 1979-)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/A+A/523/A91 : CoRoT/Exoplanet fields with MATISSE (Gazzano+, 2010)J/A+A/487/373 : Spectroscopic parameters of 451 HARPS-GTO stars (Sousa+, 2008)J/ApJS/168/297 : Stellar parameters of nearby cool stars (Takeda+, 2007)J/ApJS/162/207 : Radial velocities of solar-type stars (Abt+, 2006)J/ApJS/159/141 : Spectroscopic properties of cool stars.
