cds-question@unistra.frspectroscopic-binary-starsradial-velocityNew close sub-systems are discovered in wide physical multiple stars. Elements of spectroscopic orbits are given for the components of quadruple systems ADS 1315C, 3608C, 3824C, 3991A and for the components of triple systems ADS 1849A, 6646A, 8861A. Physical parameters (magnitudes, spectral types, masses of individual components, distances to the systems, angular separations) are estimated by combining all available data. The nearby M dwarf ADS 8861A = Gliese 507A is a good candidate for speckle resolution. The very hot white dwarf discovered by Hodgkin et al. (1993) is likely to be an additional visual component to ADS 3824C, so this system may be quintuple; however, a search of 2.993d photometric periodicity possibly caused by the hot close companion is highly desirable.1997A&AS..121...71Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/121/71CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/124/75 : Multiple star catalogue (MSC) (Tokovinin 1997-1999)J/A+AS/136/373 : Orbits of 8 multiples (Tokovinin, 1999)J/PAZh/24/343 : New spectroscopic components (Tokovinin, 1998)J/A+A/374/227 : Radial velocity in multiple systems (Tokovinin+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/121/71https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/121/71http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/121/71https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/121/71https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/121/71http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/121/71GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/121/71/table4Radial velocities and residualsADSADS namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
