cds-question@unistra.frmultiple-starsvisible-astronomytrigonometric-parallaxastrometryOrbits of inner and outer subsystems in 13 triple or higher-order stellar systems are computed or updated using position measurements and, in three cases, radial velocities. The goal is to determine mutual orbital inclinations, period ratios, and masses to complement the statistics of hierarchical systems. The effect of the subsystems on the motion in the outer orbits (wobble) is explicitly modeled to determine inner mass ratios. Stars studied here (HD 5408, 8036, 9770, 15089, 29310, 286955, 29316, 140538, 144362, 154621, 156034, 185655, and 213235) are bright and nearby (from 15pc to 150pc). Their inner periods range from 1.7yr to 49yr, and the outer periods from 83 to 2400yr. Some long-period outer orbits are poorly constrained. Four astrometric inner orbits and one outer orbit are computed for the first time.2021AJ....161..144Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/144CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/A+A/341/121 : Visual binary orbits and masses (Soederhjelm 1999)J/A+A/356/141 : BV photometry for components of HIP doubles (Fabricius+, 2000)J/A+A/382/118 : Spectroscopic sub-systems in multiple stars (Tokovinin+, 2002)J/ApJ/652/681 : Spectroscopic subcomponents in multiple systems (Docobo+, 2006)J/ApJS/208/9 : Intrinsic colors and temperatures of PMS stars (Pecaut+, 2013)J/MNRAS/449/3160 : Stellar multiplicity and debris discs (Rodriguez+, 2015)J/AJ/150/50 : Speckle interferometry at SOAR in 2014 (Tokovinin+, 2015)J/AJ/152/138 : Orbits based on speckle interferometry at SOAR (Tokovinin,2016)J/AJ/151/153 : Speckle interferometry at SOAR in 2015 (Tokovinin+, 2016)J/AJ/153/208 : LCES HIRES/Keck radial velocity Exoplanet Survey (Butler+,2017)J/ApJ/844/103 : Orbit alignment in triple stars (Tokovinin, 2017)J/ApJ/838/54 : Accurate astrometry & RVs, 4 multiple systems (Tokovinin+,2017)J/A+A/619/A81 : Multiplicity among solar-type stars.
