cds-question@unistra.frmultiple-starsorbitsstellar-spectral-typesproper-motionsradial-velocitystellar-massesSpectroscopic orbits are computed for inner pairs in nine hierarchical multiple systems (HIP 19639, 60845, 75663, 76816, 78163, 78416, 80448, 84789, and HD 105080) and for one simple binary HIP 61840. All subsystems are double-lined, and their periods range from 2.27 to 30.4 days. Five spectroscopic binaries are twins with equal masses. Each hierarchical system is discussed individually, providing estimates of outer periods, masses, orbital inclination, and axial rotation. For systems with three resolved visual components (HIP 60845 and 80448), the outer and inner visual orbits are determined, complementing the description of their architecture. The radial velocities of HIP 75663A, 76816B, and 78163B are found to be variable with long periods, implying that these hierarchies are 2 + 2 quadruples. The period-eccentricity relation for spectroscopic subsystems is discussed.2018AJ....156..194Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/194CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/135 : Henry Draper Catalogue and Extension (Cannon+ 1918-1924; ADC 1989)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AJ/123/1023 : Binary star orbits (Seymour+, 2002)J/other/AstBu/62.339 : Speckle interferometry of nearby multiplesJ/AJ/152/10 : Spectroscopy of subsystems in four multiple starsJ/AJ/152/11 : Orbits of four triple stars (Tokovinin, 2016)J/AJ/154/110 : Orbits based on SOAR speckle interferometry.
