cds-question@unistra.frpre-main-sequence-starsyoung-stellar-objectsultraviolet-photometryWe analyze 359 ultraviolet tiles from the All Sky Imaging Survey of the space mission GALEX covering roughly 400 square degrees toward the Orion star-forming region. There are a total of 1555174 ultraviolet sources that were cross-matched with other catalogs (2MASS, UCAC4, SDSS, DENIS, CMC15, and WISE) to produce a list of 290717 reliable sources with a wide range of photometric information. Using different color selection criteria, we identify 111 young stellar object candidates showing both ultraviolet and infrared excesses, of which 81 are new identifications. We discuss the spatial distribution, the spectral energy distributions, and other physical properties of these stars. Their properties are, in general, compatible with those expected for T Tauri stars. This population of TTS candidates is widely dispersed around the Orion molecular cloud.2014A&A...572A..89Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/572/A89CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/denis : The DENIS database (DENIS Consortium, 2005)I/327 : Carlsberg Meridian Catalog 15 (CMC15) (CMC, 2011)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/328 : AllWISE Data Release (Cutri+ 2013)V/139 : SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)J/A+A/508/1313 : Orion pre-main sequence RIJH light curves (Frasca+, 2009)J/AJ/144/192 : Spitzer survey of Orion A and B.
