cds-question@unistra.frspectroscopic-binary-starslate-type-starsradial-velocitySpectroscopic orbital elements are determined for 15 stars with periods from 8 to 6528days with six orbits computed for the first time. Improved astrometric orbits are computed for two stars and one new orbit is derived. Visual orbits were previously determined for four stars, four stars are members of multiple systems, and five stars have Hipparcos "G" designations or have been resolved by speckle interferometry. For the nine binaries with previous spectroscopic orbits, we determine improved or comparable elements. For HD28271 and HD200790, our spectroscopic results support the conclusions of previous authors that the large values of their mass functions and lack of detectable secondary spectrum argue for the secondary in each case being a pair of low-mass dwarfs. The orbits given here may be useful in combination with future interferometric and Gaia satellite observations.2016AJ....152...46Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/276 : Tycho Double Star Catalogue (TDSC) (Fabricius+ 2002)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/106 : MK Classification of Visual Multiples (Abt, 1981)J/AJ/145/41 : RVs of 33 spectroscopic binaries (Katoh+, 2013)J/AJ/144/56 : Speckle interferometry at SOAR in 2012 (Tokovinin+, 2012)J/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/ApJS/180/117 : MK classifications of spectroscopic binaries (Abt, 2009)J/AJ/135/209 : Velocities of 761 HIP giants (Massarotti+, 2008)J/ApJS/162/207 : Radial velocities of solar-type stars (Abt+, 2006)J/ApJS/141/503 : RVs for 889 late-type stars (Nidever+, 2002)J/A+A/374/227 : Radial velocity in multiple systems (Tokovinin+, 2001)J/ApJS/59/95 : Visual multiples.
