cds-question@unistra.frm-starsvisible-astronomytrigonometric-parallaxWe have obtained high resolution spectra for a volume-limited sample of 118 field M dwarfs. From these observations we derive projected rotational velocities and fluxes in the H{alpha} and H{beta} lines. 8 stars are double-lined spectroscopic binaries with measured or probable periods short enough for rotation to be tidally synchronized with the orbit, and another 11 are visual binaries where we cannot yet separate the lines of the two stars. Of the remaining 99 stars, 24 have rotational velocities above our detection limit of ~2km/s, and some are quite fast rotators, including two with vsini>30km/s and one with vsini~50km/s. Given the small radii of M dwarfs, these moderate rotational velocities correspond to rather short maximum rotational periods, of only 7-8 hours.1998A&A...331..581Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/331/581CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/331/581https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/331/581http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/331/581https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/331/581https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/331/581http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/331/581GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/331/581/table2 (Basic parameters of the stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/331/581/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/331/581/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/331/581/table2?GETtext/xml+votable180.050000true1.677917-7.5456940.0055555555555555566/22 131 546 811 2737 3020 3345 3715 3791 4444 4708 5000 5420 5534 5590 5853 6277 6552 6672 7103 7264 7512 7810 8023 10027 10149 10303 11636 12454 12679 13301 13451 13688 13743 14266 14772 14993 15311 15346 15602 15960 16041 17348 18195 18496 18666 18761 19466 19777 20071 20100 20459 21953 22014 22148 22289 22309 22325 22645 22709 22807 23564 23735 23910 23997 25363 26279 26327 26538 26560 26583 26972 27201 27392 27459 27462 27762 28018 28343 28646 29458 29684 30505 30771 30833 31087 31781 32115 32229 32335 44921 44937https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/331/581?format=asciiOpticaldefaultJ/A+A/331/581/table2Basic parameters of the starsSpTypeSpectral type (1)src.spTypecharrecnoRecord number assigned by the VizieR team.
