cds-question@unistra.frlate-type-starsproper-motionsvisible-astronomyphotographic-photometryinfrared-photometryradial-velocityWe present the results of spectroscopic follow-up observations for a sample of 71 red objects with high proper motions in the range 0.08-1.14 arcsec/yr as detected using APM and SuperCOSMOS Sky Surveys (SSS) measurements of multi-epoch photographic Schmidt plates. Red objects were selected by combining the photographic BjRI magnitudes with 2MASS near-infrared JHKs magnitudes. Some 50 of the 71 spectroscopically classified objects turn out to be late-type (>M6) dwarfs and in more detail, the sample includes 35 ultracool dwarfs with spectral types between M8 and L2, some previously reported, as well as five M-type subdwarfs, including a cool esdM6 object, SSSPM J0500-5406. Distance estimates based on the spectral types and 2MASS J magnitudes place almost all of the late-type (>M6) dwarfs within 50pc, with 25 objects located inside the 25pc limit of the catalogue of nearby stars. Most of the early-type M dwarfs are located at larger distances of 100-200pc, suggesting halo kinematics for some of them. All objects with Halpha equivalent widths larger than 10 Angstroms have relatively small tangential velocities (<50km/s). Finally, some late-type but blue objects are candidate binaries.2005A&A...440.1061Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/440/1061CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/421/763 : Liverpool-Edinburgh High-PM Catalogue (Pokorny+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/440/1061https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/440/1061http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/440/1061https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/440/1061https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/440/1061http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/440/1061GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/440/1061/main (List of new, red proper motion objects (table1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/440/1061/main?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/440/1061/main?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/440/1061/main?GETtext/xml+votable180.050000true1.4519167-21.95547220.0055555555555555566/4593 16434 16440 16528 16539 16568 16609 16631 16639 17096 17965 17985 18060 18666 19255 22535 22739 24652 24703 24887 24897 24992 26274 33002 33285 33431 33481 33695 33702 33883 33984 34094 34456 34535 34981 35020 35022 35099 35145 35175 35297 35299 35412 35566 35864 35923 36142 36458 36532 39140 40297 40669 43875 43966 44251 44362 45116 45370 45382 45394 45407 45637 46013 46022 46054 46203 46276 46301 46373 46376 46423 46498 46729 46745 47358 47512 48593 487498.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/440/1061?format=asciiOpticalInfrareddefaultJ/A+A/440/1061/mainList of new, red proper motion objects (table1)recnoRecord number assigned by the VizieR team.
