cds-question@unistra.frdwarf-starsproper-motionsvisible-astronomytrigonometric-parallaxinfrared-photometryWe present low-resolution spectroscopic observations of faint proper-motion stars from the LHS Catalogue, concentrating on stars with m_r_>16.5 and {mu}>0.5"/yr. The present paper includes observations and spectral classifications for 294 M dwarfs, M subdwarfs (sdM), and extreme M subdwarfs (esdM). We also identify white dwarfs among the faintest LHS stars. We have cross-referenced this sample against the Two Micron All Sky Survey (2MASS) sources, and list data for the detected objects. We discuss stars of individual interest, as well as the characteristics of the overall sample. As expected, a significant number of the stars in this proper-motion-selected sample are halo subdwarfs, including an esdM dwarf, LHS 3481, that is likely to lie within 20pc of the Sun. None of the subdwarfs show H{alpha} emission.2005PASP..117..676Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/117/676CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/87B : LHS Catalogue, 2nd Edition (Luyten 1979)I/279 : Revised Luyten Half-Second Catalogue (Bakos+ 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/117/676https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/117/676http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/117/676https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/117/676https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/117/676http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/117/676GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/117/676/table2 (Red dwarfs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/117/676/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/117/676/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/117/676/table2?GETtext/xml+votable180.050000true67.71892528.19956110.005555555555555556Cone search capability for table J/PASP/117/676/table4 (White dwarfs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/117/676/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/117/676/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/117/676/table4?GETtext/xml+votable180.050000true9.0599167-41.95722220.005555555555555556Cone search capability for table J/PASP/117/676/table6 (Parallax stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/117/676/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/117/676/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/117/676/table6?GETtext/xml+votable180.050000true30.717325.70582750.0055555555555555566/5 8 262 265 356 380 413 419 441 582 910 939 1084 1155 1668 1672 1729 2114 2265 2286 2297 2545 2655 3661 3837 4042 4064 4142-4143 4157 4333 4409 4455 4458 4756 4768 4825 4829 5068 5098 5225 5304 5409-5410 5415 5469 5487 5578 5672 5681 5783 6086 6126 6207 6410 6423 6689 6945 7516 7867 7895 7938 8131 8199 8348 8405 8431 8531 8536 8580 8685 8694 8697 8777 8783 8811 8877 8893 8939 9030 9062 9146 9203 9272 9454 9467 9477 9616 9672 9722-9723 9835 9930 9952 10214 10266 10370 10384 10407 10554 10627 10753 10788 10850 10918 11245 11496 11587 11648 11941 12027 12070 12153 12255 12576 12807 13470 13576 13676 13686 13892 14050 14123 14614 15071 15239 15530 15543 15576 15743 16125 16384 16443 16614 16746 16781 16800 16859 16864-16865 16909 17007 17121 17130 17199 17268 17281 17292 17365-17366 17400 17452 17515 17598 17697 17699 17744 17774 17853 17900 17931 17993 18089 18185 18210 18261 18385 18447 18557 18592 18609 18660 18681 18693 18722 18826 18960 19009 19072 19080 19250 19440 19475 19477 19579 19613 19786 19813 19864 19906 19932 19972 20061 20099 20108 20183 20391 21220 21866 21981 22366 22539 23167 23485 23698 23773 24171 24213 24636 24652 24691 24813 24816 25131 25140 25226 25261 25297 25304-25305 25310 25552 25690 25749 25791 25815 25839 26031 26228 26231 26250 26448 26503 26685 26807 26900 26981 27102 27130 27383 27416 27447 27540 27587 27709 27727 27894 27916 27933 27962 28109 28206 28349 28354 28446 28470 28477 28501 28633 29798 30402 30505 30587 30833 30864 30955 31022 31346 31434-31435 31452 31497 31596 31730 32428 34181 34494 34532 34722 35255 35302 35478 35596 35611 35614 35748 35969 36347 36410 36439 36441 36516 36551 36576 36770 39820 40164 40182 40306 40361 40420 40531 40789 40904 40941 42745 43848 43994 44011 44349 44564 44567 44585 44610 44632 44731 44777 44824 45055 46541 46802 46867 46879 46887 46975 46990 48210 48231 48241 48304 48344 48611 48660 48669 48778 48926 49103https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/117/676?format=asciiOpticalInfrareddefaultJ/PASP/117/676/table2Red dwarfsrecnoRecord number assigned by the VizieR team.
