cds-question@unistra.frspectroscopic-binary-starsm-starsdwarf-starsradial-velocityproper-motionsvisible-astronomytrigonometric-parallaxspectroscopyWe present the spectroscopic orbits of 11 nearby, mid-to-late M dwarf binary systems in a variety of configurations: 2 single-lined binaries (SB1s), 7 double-lined binaries (SB2s), 1 double-lined triple (ST2), and 1 triple-lined triple (ST3). Eight of these orbits are the first published for these systems, while five are newly identified multiples. We obtained multi-epoch, high-resolution spectra with the TRES instrument on the 1.5m Tillinghast Reflector at the Fred Lawrence Whipple Observatory located on Mt. Hopkins in AZ. Using the TiO molecular bands at 7065-7165{AA}, we calculated radial velocities for these systems, from which we derived their orbits. We find LHS 1817 to have in a 7hr period a companion that is likely a white dwarf, due to the ellipsoidal modulation we see in our MEarth-North light-curve data. We find G123-45 and LTT11586 to host companions with minimum masses of 41MJup and 44MJup with orbital periods of 35 and 15days, respectively. We find 2MA0930+0227 to have a rapidly rotating stellar companion in a 917 day orbital period. GJ268, GJ1029, LP734-34, GJ1182, G258-17, and LTT7077are SB2s with stellar companions with orbital periods of 10, 96, 34, 154, 5, and 84days; LP655-43 is an ST3 with one companion in an 18day orbital period and an outer component in a longer undetermined period. In addition, we present radial velocities for both components of L870-44AB and for the outer components of LTT11586 and LP655-43.2020AJ....159..290Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/290CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AJ/124/1144 : Orbits of 171 single-lined spectro. binaries (Latham, 2002)J/ApJS/141/503 : Radial Velocities for 889 late-type stars (Nidever+, 2002)J/AJ/123/2822 : Photometry of southern NLTT stars (Reid+, 2002)J/ApJ/704/975 : Rotational velocities for M dwarfs (Jenkins+, 2009)J/ApJ/720/1118 : i-band photometry of HAT-P-16 (Buchhave+, 2010)J/ApJS/190/1 : A survey of stellar families (Raghavan+, 2010)J/ApJ/742/123 : Photometry and Velocity of LSPM J1112+7626 (Irwin+, 2011)J/ApJ/757/112 : Stellar diameters.
