cds-question@unistra.frmultiple-starsradial-velocityspectroscopic-binary-starsThis work extends the still modest number of multiple stars with known relative orbit orientation. Accurate astrometry and radial velocities are used jointly to compute or update outer and inner orbits in three nearby triple systems, HIP 101955 (orbital periods 38.68 and 2.51yr), HIP 103987 (19.20 and 1.035yr), HIP 111805 (30.13 and 1.50yr), and in one quadruple system, HIP 2643 (periods 70.3, 4.85, and 0.276yr), all composed of solar-type stars. The masses are estimated from the absolute magnitudes and checked using the orbits. The ratios of outer to inner periods (from 14 to 20) and the eccentricities of the outer orbits are moderate. These systems are dynamically stable, but not very far from the stability limit. In three systems, all orbits are approximately coplanar and have small eccentricity, while in HIP101955 the inner orbit with e=0.6 is highly inclined.2017ApJ...838...54Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/838/54CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/A+A/341/121 : Visual binary orbits and masses (Soederhjelm 1999)J/AJ/121/3224 : Speckle interferometry of HIP binaries (Mason+, 2001)J/BaltA/11/153 : HIP visual binaries kinematics.
