cds-question@unistra.frspectroscopic-binary-starsradial-velocityWith extensive sets of new radial velocities we have determined orbital elements for three previously known spectroscopic binaries, HD 54371, HR 2692, and 16 UMa. All three systems have had the lines of their secondaries detected for the first time. The orbital periods range from 16.24 to 113.23days, and the three binaries have modestly or moderately eccentric orbits. The secondary to primary mass ratios range from 0.50 to 0.64. The orbital dimensions (a_1_sini and a_2_sini) and minimum masses (m_1_sin^3^i and m_2_sin^3^i) of the binary components all have accuracies of {<=}1%. With our spectroscopic results and the Hipparcos data, we also have determined astrometric orbits for two of the three systems, HR 2692 and 16 UMa. The primaries of HD 54371 and 16 UMa are solar-type stars, and their secondaries are likely K or M dwarfs. The primary of HR 2692 is a late-type subgiant and its secondary is a G or K dwarf. The primaries of both HR 2692 and 16 UMa may be pseudosynchronously rotating, while that of HD 54371 is rotating faster than its pseudosynchronous velocity.2015AJ....149...63Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)J/AJ/146/129 : Orbits of 4 double-lined spectroscopic binaries (Fekel+, 2013)J/AJ/145/111 : Radial velocities of 5 spectroscopic binaries (Fekel+, 2013)J/AJ/145/41 : Radial velocities of 33 spectroscopic binaries (Katoh+, 2013)J/ApJS/180/117 : MK classifications of spectroscopic binaries (Abt, 2009)J/ApJ/695/1527 : HR 8257: orbit and basic properties (Fekel+, 2009)J/A+A/442/365 : Astrometric orbits of SB9 stars (Jancart+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/63https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/149/63/table1 (Basic properties of the program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/63/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/63/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/63/table1?GETtext/xml+votable180.050000true107.397459225.72864970.0055555555555555566/6273 7390 239213.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/149/63?format=asciiOpticaldefaultJ/AJ/149/63/table1Basic properties of the program starsrecnoRecord number assigned by the VizieR team.
