cds-question@unistra.frproper-motionsinfrared-photometryspectroscopyWe have combined near-infrared data from the Two Micron All Sky Survey with ancillary optical data to identify previously unrecognized proper-motion stars that have colors and magnitudes consistent with nearby M dwarfs. We present follow-up observations of 392 stars from that sample, including ~200 stars discussed here for the first time. Our distance estimates, based primarily on spectroscopic parallaxes, place 123 stars within 20pc of the Sun. One hundred and seventy-six stars exhibit H{alpha} emission, and 82 stars have plausible X-ray counterparts from ROSAT observations.2007AJ....133.2825Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2825CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/123/2806 : Nearby stars in the NLTT catalogue (Reid+, 2002)J/AJ/123/2822 : Photometry of southern NLTT stars (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 NLTT catalogue (Reid+, 2004)J/AJ/133/439 : Luminosity function of M7-L8 ultracool dwarfs (Cruz+, 2007)J/AJ/136/1290 : Ultracool dwarfs from the 2MASS (Reid+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/2825https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/2825http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/2825https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/2825https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/2825http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/2825GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/2825/table2 (Spectroscopy of previously catalogued stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2825/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2825/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2825/table2?GETtext/xml+votable180.050000true8.22125-4.5683330.005555555555555556Cone search capability for table J/AJ/133/2825/table3 (Spectroscopy of additional nearby star candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2825/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2825/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2825/table3?GETtext/xml+votable180.050000true1.663333-7.0927780.0055555555555555566/265 483 596 608 804 997 1019 1023 1052 1199 1635 1673 1690 1722 2104 2198 2250 2398 2425 2462 2516 2586 2793 2830 2880 4349 4421 4629 4654 4764 4770 4813 4869 4887 4932 5039 5041 5224 5351 5429 5819 6003 6348 6600 6888 7509 7510 7528 7606 7874 7900 7956 8381 8507 8601 8763 8909 9183 9374 9387 9429 9445 9636 9680 9768 9779 9880 9917 9926 10145 10356 10374 10405 10414 10416 10420 10449 10484 10500 10602 10612 10701 10747 11208 11336 11373 11473 11480 11797 11852 11864 11910 11963 11986 12090 12567 12605 12878 12892 13182 13708 13748 13749 14490 14777 14858 14921 14935 15356 15896 16412 16459 16476 16576 16596 16752 16809 16824 16827 16830 16993 17045 17059 17097 17283 17339 17342 17349 17351 17400 17509 17513 17602 17606 17607 17631 17663 17832 17932 17964 18003 18503 18585 18726 18727 18742 18762 18838 18949 18977 19075 19755 19770 20064 20134 20282 20381 20472 20544 21310 21359 21407 21416 21438 21838 21890 22390 22550 22603 22621 22639 22683 22719 22720 22728 22731 22803 22811 22845 22862 22867 23111 23125 23510 23534 23881 24119 24193 24231 24747 24897 24928 24935 24938 24944 25001 25384 25440 25450 25637 25638 25727 25818 25933 25999 26127 26181 26254 26255 26755 26943 27611 27886 27910 27937 28005 28115 28197 28406 28589 28935 28996 29025 29334 29348 29744 30007 30011 30091 31400 31960 32058 32136 32149 32157 32274 32367 32391 32699 32861 32954 33038 33065 33071 33085 33088 33149 33159 33234 33252 33308 33339 33340 33341 33429 33805 33833 34214 34233 34391 34540 34561 34587 34680 35415 35632 35663 35673 35709 35779 35815 35943 35998 36037 36141 36185 36224 36260 36268 36285 36323 36359 36390 36460 36528 36624 36625 36627 36636 36697 36793 36800 36801 36827 37377 37389 37419 37423 37519 37544 37566 38932 38934 39548 39628 40341 40662 40702 40815 40887 40932 42863 42873 42981 42984 42999 43481 43893 43941 43961 44026 44186 44187 44197 44387 44392 44431 44449 44583 44628 44662 44696 44776 45035 45046 46497 46615 46665 46704 46949 47016 47019 47050 47450 47486 47535 47536 47538 47614 47681 47921 47925 47959 48110 48124 48158 48176 48178 48179 48189 48248 48252 48260 48270 48281 48287 48320 48358 48361 48365 48380 48444 48527 48631 48644 48683 48701 48704 48715 48723 48801 48815 48833 48845 48954 48980 49018 49146 491471.1166583743361574e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/2825?format=asciiInfrareddefaultJ/AJ/133/2825/table2Spectroscopy of previously catalogued starsrecnoRecord number assigned by the VizieR team.
