cds-question@unistra.frm-starsultraviolet-photometryline-intensitiesproper-motionsstellar-spectral-typesstellar-distanceWe present a catalog of Galaxy Evolution Explorer Near-UV (NUV) and Far-UV (FUV) photometry for the Palomar/MSU and SDSS DR7 spectroscopic M dwarf catalogs. The catalog contains NUV measurements matched to 577 spectroscopically confirmed M dwarfs and FUV measurements matched to 150 spectroscopically confirmed M dwarfs. Using these data, we find that NUV and FUV luminosities strongly correlate with H{alpha} emission, a typical indicator of magnetic activity in M dwarfs. We also examine the fraction of M dwarfs with varying degrees of strong line emission at NUV wavelengths. Our results indicate that the frequency of M dwarf NUV emission peaks at intermediate spectral types, with at least ~30% of young M4-M5 dwarfs having some level of activity. For mid-type M dwarfs, we show that NUV emission decreases with distance from the Galactic plane, a proxy for stellar age. Our complete matched source catalog is available online.2016ApJ...817....1Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/817/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)J/ApJ/798/41 : GALEX NUV observations of bright M-type stars (Ansdell+, 2015)J/AJ/148/64 : HAZMAT I.
