cds-question@unistra.frinfrared-photometryyoung-stellar-objectsmolecular-cloudsextinctionNormal field stars located behind dense clouds are a valuable resource in interstellar astrophysics, as they provide continua in which to study phenomena such as gas-phase and solid-state absorption features, interstellar extinction, and polarization. This paper reports the results of a search for highly reddened stars behind the Taurus Dark Cloud complex. We use the Two Micron All Sky Survey (2MASS) Point Source Catalog to survey a ~50deg^2^ area of the cloud to a limiting magnitude of Ks=10.0. Photometry in the 1.2-2.2um passbands from 2MASS is combined with photometry at longer infrared wavelengths (3.6-12um) from the Spitzer Space Telescope and the Infrared Astronomical Satellite to provide effective discrimination between reddened field stars and young stellar objects (YSOs) embedded in the cloud. Our final catalog contains 248 confirmed or probable background field stars, together with estimates of their total visual extinctions, which span the range 2<A_V_<29mag. We also identify the 2MASS source J04292083+2742074 (IRAS 04262+2735) as a previously unrecognized candidate YSO, based on the presence of infrared emission greatly in excess of that predicted for a normal reddened photosphere at wavelengths >5um.2008ApJS..176..457Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/176/457CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)J/ApJ/647/1180 : Infrared photometry of Taurus SFR (Luhman+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/176/457https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/176/457http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/176/457https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/176/457https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/176/457http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/176/457GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/176/457/table (Catalog of reddened field stars and associated data (table 1 and 2 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/176/457/table?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/176/457/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/176/457/table?GETtext/xml+votable180.050000true62.11137528.06191670.0055555555555555565/262 263 270 6/375 1031 1036 1037 1039 1042 1043 1044 1046 1047 1059 1061 1063 1065 1066 1068 1073 1074 1075 1076 1078 1084 1085 1088 1090 1096 1159 1164 1165 1168 1169 1170 1174 1176 11788.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/176/457?format=asciiInfrareddefaultJ/ApJS/176/457/tableCatalog of reddened field stars and associated data (table 1 and 2 of the paper)recnoRecord number assigned by the VizieR team.
