Abstract
We present radial velocities of the M8V-type, very low-mass star vB10 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 KeckII telescope. Our data suggest that vB10 shows radial velocity variability with an amplitude of ∼1 kms -1, 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. © 2009 ESO.
