cds-question@unistra.frm-starsdwarf-starsstellar-distancevisible-astronomytrigonometric-parallaxinfrared-photometryphotometryproper-motionsWe present 160 new trigonometric parallaxes for 151 M dwarf systems from the REsearch Consortium On Nearby Stars (RECONS) group's long-term astrometry/photometry program at the CTIO/SMARTS 0.9m telescope. Most systems (124 or 82%) are found to lie within 25pc. The stars have 119mas/yr{<=}{mu}{<=}828mas/yr and 3.85{<=}(V-K){<=}8.47. Among these are 58 systems from the SuperCOSMOS-RECONS search, discovered via our proper motion trawls of the SuperCOSMOS digitized archival photographic plates, while the remaining stars were suspected via photometric distance estimates to lie nearby. Sixteen systems were newly discovered via astrometric perturbations to be binaries, many of which are ideal for accurate mass determinations due to their proximity and orbital periods on the order of a decade. A variability analysis of the stars presented, two-thirds of which are new results, shows six of the stars to vary by more than 20mmag. This effort brings the total number of parallaxes for M dwarf systems measured by RECONS to nearly 500 and increases by 26% the number of southern M dwarf systems with accurate trigonometric parallaxes placing them within 25pc.2017AJ....153...14Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (Voges+ 2000)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)J/AJ/152/141 : Solar neighborhood.
