cds-question@unistra.frlate-type-starsstellar-flaresWe have identified 63 flares on M dwarfs from the individual component spectra in the Sloan Digital Sky Survey (SDSS) using a novel measurement of emission-line strength called the Flare Line Index. Each of the ~38000M dwarfs in the SDSS low-mass star spectroscopic sample of West et al. (2008, Cat. J/AJ/135/785) was observed several times (usually 3-5) in exposures that were typically 9-25 minutes in duration. Our criteria allowed us to identify flares that exhibit very strong H{alpha} and H{beta} emission-line strength and/or significant variability in those lines throughout the course of the exposures. The flares we identified have characteristics consistent with flares observed by classical spectroscopic monitoring.2010AJ....140.1402Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/140/1402CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/135/785 : SDSS-DR5 low-mass star spectroscopic sample (West+, 2008)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/140/1402https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/140/1402http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/140/1402https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/140/1402https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/140/1402http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/140/1402GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/140/1402/table3 (Properties of the flares in the SDSS spectroscopic sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/140/1402/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/140/1402/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/140/1402/table3?GETtext/xml+votable180.050000true40.7191.056280.0055555555555555566/4096 4128 4196 4230 4734 4892 4893 4924 5096 5353 5507 5549 5650 5710 5802 6220 6254 6358 6359 6403 6555 6566 7440 9231 9422 9738 9744 9770 9801 9860 9975 9979 10553 10572 10732 10850 11433 11446 11504 17755 17819 17826 17840 18028 18067 18074 18083 18605 18775 18776 22012 23050 26083 26321 26498 27307 27363 27746 27970 28614 28644 28658 28671https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/140/1402?format=asciiOpticaldefaultJ/AJ/140/1402/table3Properties of the flares in the SDSS spectroscopic samplerecnoRecord number assigned by the VizieR team.
