Using the data from NEOWISE, along with the AllWISE catalog, Schneider et al. (2016, J/ApJ/817/112) conducted an all-sky proper motion survey to search for nearby objects with high proper motions. Here, we present a follow-up spectroscopic survey of 65 of their discoveries, which focused primarily on potentially nearby objects (d<25 pc), candidate late-type brown dwarfs (>=L7), and subdwarf candidates. We found 31 new M dwarfs, 18 new L dwarfs, and 11 new T dwarfs. Of these, 13 are subdwarfs, including one new sdL1 and two new sdL7s. Eleven of these discoveries, with spectral types ranging from M7 to T7 (including one subdwarf) are predicted to be within 25 pc, adding to the number of known objects in the solar neighborhood. We also discovered three new early-type T subdwarf candidates, one sdT1, one sdT2, and one sdT3, which would increase the number of known early-type T subdwarfs from two to five.2019AJ....158..182Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/182CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)J/ApJ/817/112 : NEOWISE/AllWISE high proper motion objects (Schneider+, 2016)J/ApJS/224/36 : The AllWISE motion survey (AllWISE2) (Kirkpatrick+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/182https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/182http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/182https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/182https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/182http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/182GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/182/catalog (Summary of observations (table 1) , spectral types (table 3) , object distances (table 4) , photometry and other parameters (table 5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/182/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/182/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/182/catalog?GETtext/xml+votable180.050000true1.1277311-26.06656310.005555555555555556Cone search capability for table J/AJ/158/182/table2 (Subdwarf standards)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/182/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/182/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/182/table2?GETtext/xml+votable180.050000true95.311920365.97115080.0055555555555555566/723 840 1059 1680 4166 5955 5957 6423 6696 6794 7049 7849 8783 9467 11224 11250 11830 12812 15215 16494 16583 16589 16616 16706 17081 17179 17268 17841 18129 18180 18204 18919 19802 20672 21123 23220 23235 23684 24137 25555 25798 26150 26186 26667 26820 26987 27685 27726 28521 29158 29192 29321 29378 31219 31313 31657 31797 32178 32574 33565 33616 33746 36081 36184 38495 38830 40193 40706 40887 40954 41028 44349 44564 44614 44862 44941 44949 45935 46889 47089 484833.830199579824256e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/182?format=asciiInfrareddefaultJ/AJ/158/182/catalogSummary of observations (table 1) , spectral types (table 3) , object distances (table 4) , photometry and other parameters (table 5)spspectrummeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
