cds-question@unistra.frstellar-flareshst-photometryvariable-starsWe utilize the Sagittarius Window Eclipsing Extrasolar Planet Search Hubble Space Telescope/Advanced Camera for Surveys data set for a Deep Rapid Archival Flare Transient Search (DRAFTS) to constrain the flare rate toward the older stellar population in the Galactic bulge. During seven days of monitoring 229293 stars brighter than V=29.5, we find evidence for flaring activity in 105 stars between V=20 and V=28. We divided the sample into non-variable stars and variable stars whose light curves contain large-scale variability. The flare rate on variable stars is ~700 times that of non-variable stars, with a significant correlation between the amount of underlying stellar variability and peak flare amplitude. The flare energy loss rates are generally higher than those of nearby well-studied single dMe flare stars.2012ApJ...754....4Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/754/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)J/ApJS/207/15 : M dwarf flare spectra (Kowalski+, 2013)J/AJ/141/50 : White-light flares on Kepler cool stars (Walkowicz+, 2011)J/AJ/140/1402 : M dwarf flares from SDSS spectra (Hilton+, 2010)J/other/A+ARV/17.251 : Stars observed with Doppler imaging (Strassmeier, 2009)J/ApJ/685/463 : ChaMPlane X-ray sources in the Galactic bulge (Koenig+, 2008)J/ApJS/173/673 : M dwarf UV flares in GALEX (Welsh+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/754/4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/754/4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/754/4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/754/4https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/754/4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/754/4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/754/4/table3 (Properties of DRAFTS flaring stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/754/4/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/754/4/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/754/4/table3?GETtext/xml+votable180.050000true269.7224167-29.19793890.0055555555555555566/288642.3657755224268815e-19 3.5452907792336973e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/754/4?format=asciiOpticaldefaultJ/ApJ/754/4/table3Properties of DRAFTS flaring starsrecnoRecord number assigned by the VizieR team.
