cds-question@unistra.frdwarf-starsproper-motionsstellar-spectral-typesvisible-astronomytrigonometric-parallaxWe report trigonometric parallaxes for 134 low-mass stars and brown dwarfs, of which 38 have no previously published measurement and 79 more have improved uncertainties. Our survey focused on nearby targets, so 119 are closer than 30pc. Of the 38 stars with new parallaxes, 14 are within 20pc and seven are likely brown dwarfs (spectral types later than L0). These parallaxes are useful for studies of kinematics, multiplicity, and spectrophotometric calibration. Two objects with new parallaxes are confirmed as young stars with membership in nearby young moving groups: LP 870-65 in AB Doradus and G161-71 in Argus. We also report the first parallax for the planet-hosting star GJ3470; this allows us to refine the density of its Neptune-mass planet. T-dwarf 2MASSJ12590470-4336243, previously thought to lie within 4pc, is found to be at 7.8pc, and the M-type star 2MASSJ01392170-3936088 joins the ranks of nearby stars as it is found to be within 10pc. Five stars that are overluminous and/or too red for their spectral types are identified and deserve further study as possible young stars.2016AJ....152...24Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/24CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)J/AJ/147/94 : Solar neighborhood.
