cds-question@unistra.frlate-type-starsradial-velocityinfrared-astronomyspectroscopyWe present radial velocities of the M8V-type, very low-mass star vB 10 obtained at four different epochs between 2001 and 2008. We use high-resolution (R~20000) near-infrared (J-band) spectra taken with the NIRSPEC instrument on the Keck II telescope. Our data suggest that vB 10 shows radial velocity variability with an amplitude of ~1km/s, a result that is consistent with the recent finding of a massive planet companion around the star. More velocity measurements and a better sampling of the orbital phase are required to precisely constrain the orbital parameters and the individual masses of the pair.2009A&A...505L...5Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/505/L5CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/505/L5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/505/L5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/505/L5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/505/L5https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/505/L5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/505/L5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/505/L5/table2NIRSPEC radial velocity measurements of vB 10recnoRecord number assigned by the VizieR team.
