cds-question@unistra.fropen-star-clusterspre-main-sequence-starsinfrared-photometryinfrared-astronomyspectroscopyWe present a drift-scan survey covering a ~5{deg}x5{deg} region toward the southern portion of the Taurus-Auriga molecular cloud. Data taken in the B,R,I filters with the Quest-2 camera on the Palomar 48 inch (1.2m) Samuel Oschin Telescope were combined with Two Micron All Sky Survey near-infrared photometry to select candidate young stars. Follow-up optical spectroscopy of 190 candidates led to the identification of 42 new low-mass pre-main-sequence stars with spectral types M4-M8, of which approximately half exhibit surface gravity signatures similar to known Taurus stars, while the other half exhibit surface gravity signatures similar to members of the somewhat older Upper Scorpius, TW Hya, and Pic associations.2006AJ....132.2665Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/2665CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/312/439 : New T Tauri stars in Taurus-Auriga (Wichmann+, 1996)J/A+AS/101/485 : Multisite UBVRI photometry in Tau-Aur cloud (Bouvier+ 1993)J/A+AS/124/449 : Young stars south of Taurus-Auriga (Magazzu+ 1997)J/A+AS/132/173 : New weak-line T Tauri stars in Taurus-Auriga (Li+ 1998)J/A+AS/145/187 : uvby-{beta} photometry of WTTS (Chavarria-K+, 2000)J/ApJ/581/1194 : Taurus-Auriga PMS stars ages and Teff (Palla+, 2002)J/ApJS/101/117 : UBVRIJHKLMNQ photometry in Taurus-Auriga (Kenyon+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/2665https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/2665http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/2665https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/2665https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/2665http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/2665GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/2665/table1 (Measured quantities for new PMS stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/2665/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/2665/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/2665/table1?GETtext/xml+votable180.050000true51.38833324.4494720.005555555555555556Cone search capability for table J/AJ/132/2665/tablea1 (Measured quantities for candidates spectroscopically confirmed as field dwarfs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/2665/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/2665/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/2665/tablea1?GETtext/xml+votable180.050000true40.6427520.44079440.0055555555555555565/95 258 6047 6055 6059 6/349 350 351 365 370 372 375 379 430 431 435 436 437 440 442 446 454 457 463 465 469 472 481 484 488 490 603 629 769 771 777 778 782 784 786 803 805 1025 1026 1027 1029 1030 1031 1037 1039 1042 1043 1046 1048 1049 1056 1057 1059 1060 1061 1062 1064 1065 24157 24158 24167 24171 24174 24175 24177 24178 24181 24182 24183 24184 24187 24241 24242 24243 24245 24247 24249 24251 24252 24255 24259 24261 24262 24264 24268 24269 24270 24275 24276 24278 24280 24281 24292 24294 24297 24323 24330 24334 24354 24358 24360 243628.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/2665?format=asciiInfrareddefaultJ/AJ/132/2665/table1Measured quantities for new PMS starsrecnoRecord number assigned by the VizieR team.
