cds-question@unistra.frinfrared-photometryvisible-astronomybroad-band-photometrystellar-distanceWe present BVRI photometry of 180 bright, southern nearby-star candidates. The stars were selected from the New Luyten Two-Tenths proper-motion catalog (Cat. <I/98>) based on optical/infrared colors, constructed by combining Luyten's m_r_ estimates with near-infrared photometry from the Two Micron All Sky Survey (Cat. <B/2mass>) . Photometric parallaxes derived from V-Ks, V-I, and I-J colors, combined with the limited available astrometry, show that as many as 108 stars may lie within 20pc of the Sun. Of these, 53 are new to nearby-star catalogs, including three within 10pc of the Sun.2002AJ....123.2822Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/2822CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/2mass : The 2MASS database (IPAC/UMass, 2000)I/98 : NLTT Catalogue (Luyten, 1979)I/87 : LHS Catalogue, 2nd Edition (Luyten 1979)V/70 : Nearby Stars, Preliminary 3rd Version (Gliese+ 1991)J/AJ/123/2806 : Nearby stars in the NLTT catalogue (Reid+, 2002)J/AJ/123/2828 : Spectroscopy of northern NLTT stars (Cruz+, 2002)J/AJ/126/2421 : 2MASS-Selected sample of ultracool dwarfs (Cruz+, 2003)J/AJ/126/2449 : Nearby ultracool dwarfs in galactic plane (Reid+, 2003)J/AJ/126/3007 : Spectroscopy of faint red NLTT dwarfs (Reid+, 2003)J/AJ/128/463 : A preliminary 20pc census from the NLTT cat.
