cds-question@unistra.frspectroscopic-binary-starsradial-velocityWe have used precise differential astrometry from the Palomar High-precision Astrometric Search for Exoplanet Systems project and radial-velocity measurements covering a time span of 40yr to determine the orbital parameters of the 1 Geminorum triple system. We present the first detection of the spectral lines of the third component of the system, together with precise mass (0.5%) and distance (0.15%) determinations for this system. In addition, our astrometry allows us to make the first determination of the mutual inclination of the orbits.2014ApJ...783....3Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/783/3CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/140/1579 : PHASES astrometry data archive (Muterspaugh+, 2010)J/MNRAS/389/925 : Triple and quadruple stars (Tokovinin, 2008)J/ApJ/636/1020 : kappa Peg astrometry and velocities (Muterspaugh+, 2006)J/AJ/130/2866 : Differential astrometry of {delta} Equ (Muterspaugh+, 2005)J/A+A/384/1030 : Orientation of orbits in triple stars (Sterzik+, 2002)J/A+AS/124/75 : Multiple star catalogue (MSC) (Tokovinin 1997-1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/783/3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/783/3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/783/3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/783/3https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/783/3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/783/3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/783/3/velocitiesCombined table from original tablesrecnoRecord number assigned by the VizieR team.
