cds-question@unistra.frproper-motionsphotometryThe census of the solar neighbourhood is almost complete for stars and becoming more complete in the brown dwarf regime. Spectroscopic, photometric and kinematic characterization of nearby objects helps us to understand the local mass function, the binary fraction, and provides new targets for sensitive planet searches. We aim to derive spectral types and spectrophotometric distances of a sample of new high proper motion sources found with the WISE (Wide-field Infrared Survey Explorer) satellite, and obtain parallaxes for those objects that fall within the area observed by the Vista Variables in the Via Lactea survey (VVV). We used low-resolution spectroscopy and template fitting to derive spectral types, multiwavelength photometry to characterize the companion candidates and obtain photometric distances. Multi-epoch imaging from the VVV survey was used to measure the parallaxes and proper motions for three sources. We confirm a new T2 brown dwarf within ~15pc. We derived optical spectral types for 24 sources, mostly M dwarfs within 50pc. We addressed the wide binary nature of 16 objects found by the WISE mission and previously known high proper motion sources. Six of these are probably members of wide binaries, two of those are new, and present evidence against the physical binary nature of two candidate binary stars found in the literature, and eight that we selected as possible binary systems. We discuss a likely microlensing event produced by a nearby low-mass star and a galaxy, that is to occur in the following five years.2015MNRAS.454.4054Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/454/4054CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/denis : The DENIS database (DENIS Consortium, 2005)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/327 : Carlsberg Meridian Catalog 15 (CMC15) (CMC, 2011)II/337 : VISTA Variables in the Via Lactea Survey DR1 (Minniti+, 2014)II/311 : WISE All-Sky Data Release (Cutri+ 2012)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/454/4054https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/454/4054http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/454/4054https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/454/4054https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/454/4054http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/454/4054GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/454/4054/table1 (WISE high PM objects selected for spectroscopic follow-up with the EFOSC2 at the NTT at La Silla observatory, and FIRE at Baade at Las Campanas observatory)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/4054/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/4054/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/4054/table1?GETtext/xml+votable180.050000true104.3101667-14.77366670.005555555555555556Cone search capability for table J/MNRAS/454/4054/table3 (Archival photometry for sources selected for EFOSC2 spectroscopy and candidate companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/4054/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/4054/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/4054/table3?GETtext/xml+votable180.050000true190.3674661-65.13273610.005555555555555556Cone search capability for table J/MNRAS/454/4054/table5 (Binary/multiple system investigated in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/4054/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/4054/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/4054/table5?GETtext/xml+votable180.050000true104.3129167-14.77147220.0055555555555555566/20947 25966-25967 26083 27193 29896 37761 38087 38203 39211 41455 41578 41639 41694 41821 41997 43811-43812 44035 44041 44721 45632 45840 47090 47706 481938.157980699529898e-21 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/454/4054?format=asciiOpticaldefaultJ/MNRAS/454/4054/table1WISE high PM objects selected for spectroscopic follow-up with the EFOSC2 at the NTT at La Silla observatory, and FIRE at Baade at Las Campanas observatoryNameName (2MASS or WISE)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
