cds-question@unistra.frspectroscopic-binary-starsorbitsThe CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be used to measure fundamental properties of stars. Using spectroscopic observations we determine the orbital and physical properties of nine new double-line spectroscopic binary systems by analysing their radial velocity curves. We use two-dimensional cross-correlation techniques to derive the radial velocities of the targets, which are then employed to determine the orbital properties. Photometric data from the literature are also analysed to search for possible eclipses and to measure stellar variability, which can yield rotation periods. Out of the 342 stars in the CARMENES sample, only 9 have been found to be SB2s. We provide empirical orbital properties and minimum masses for the sample of spectroscopic binaries, with periods ranging from 1.13 to 8000 days and eccentricities up to ~0.54. Absolute masses are also estimated from mass-luminosity calibrations, ranging between ~0.1M_{sun}_ and ~0.6M_{sun}_. These new binary systems increase the number of double-line M dwarf binary systems with known orbital parameters by 14%, and suggest that low-mass binaries seem to have lower mass ratios than more massive systems.2018A&A...619A..32Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/619/A32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : SB9: 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-14)J/A+A/577/A128 : CARMENES input catalog of M dwarfs I (Alonso-Floriano+, 2015)J/A+A/597/A47 : CARMENES input catalog of M dwarfs II (Cortes-Contreras+ 2017)J/A+A/609/A117 : CARMENES radial velocity curves of 7 M-dwarf (Trifonov+, 2018)J/A+A/609/L5 : HD147379 b velocity curve (Reiners+, 2018)J/A+A/612/A49 : 324 CARMENES M dwarfs velocities (Reiners+, 2018)J/A+A/614/A122 : Radial-velocity of CARMENES M dwarfs (Tal-Or+, 2018)J/A+A/615/A6 : Photospheric parameters of CARMENES stars (Passegger+, 2018)J/A+A/621/A126 : CARMENES input catalogue of M dwarfs.
