cds-question@unistra.frmultiple-starsspectroscopic-binary-starsradial-velocityNew close sub-systems are reported and studied in eight visual multiple systems. Elements of one double-lined and eight single-lined spectroscopic orbits are given. Magnitudes, colors, spectral types, masses of individual components are estimated by combining all available data. The visual secondary component of the young binary HD 27638 is a double-lined pair of G-type dwarfs on a 17-day orbit with an unseen but massive (>1.2M_{sun}_) spectroscopic tertiary on an 8-year orbit. The invisible secondary of HD 28271A is also massive, but it is not seen probably owing to a high luminosity of the primary - an F7 star with fast axial rotation and active chromosphere which evolves off the Main Sequence. Two additional companions are found in the visual triple system HD 179484.2001A&A...374..227Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/374/227CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/124/75 : Multiple star catalogue (MSC) (Tokovinin 1997-1999)J/A+AS/121/71 : Orbits of 7 spect. binaries in multiples (Tokovnin, 1997)J/A+AS/136/373 : Orbits of 8 multiples (Tokovinin, 1999)J/PAZh/24/343 : New spectroscopic components (Tokovinin, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/374/227https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/374/227http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/374/227https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/374/227https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/374/227http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/374/227GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/374/227/table1 (Multiple system identification)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/374/227/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/374/227/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/374/227/table1?GETtext/xml+votable180.050000true1.56583358.4366670.0055555555555555566/1069 1216 3006 14918 15093 23191 23403 44887https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/374/227?format=asciidefaultJ/A+A/374/227/table1Multiple system identificationrecnoRecord number assigned by the VizieR team.
