cds-question@unistra.frh-ii-regionsinfrared-sourcespre-main-sequence-starsemission-line-starsBright-rimmed clouds (BRCs) found in H II regions are probably sites of triggered star formation due to compression by ionization/shock fronts. Many BRCs harbor IRAS point sources of low dust temperature. They also frequently contain a small cluster of near-IR stars that is elongated along the axis of the BRC. Here we present the results of our H{alpha} grism spectroscopy and narrowband imaging observations of BRCs in search of candidate premain-sequence stars of the T Tauri, Herbig Ae/Be and related types, and Herbig-Haro (HH) objects. We have detected a large number (460) of H{alpha} emission stars down to a limiting magnitude of about R=20 in and around all but two of the 28 BRCs observed. The present study has, for the first time, reached down nearly to the faintest classical T Tauri star population in OB associations. A total of 12 new HH objects have been found.2002AJ....123.2597Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/2597CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/104 : General Catalogue of Herbig-Haro Objects (Reipurth+, 1999)J/AJ/135/2323 : Updated and corrected Table 5 (Ikeda+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/123/2597https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/123/2597http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/123/2597https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/123/2597https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/123/2597http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/123/2597GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/123/2597/table5 (Detected H{alpha} Emission Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/2597/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/2597/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/2597/table5?GETtext/xml+votable180.050000true359.92666767.3744440.005555555555555556Cone search capability for table J/AJ/123/2597/table7 (Herbig-Haro objects in/around BRCS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/2597/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/2597/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/2597/table7?GETtext/xml+votable180.050000true37.25458361.5591670.0055555555555555565/3869 6/3290 3300-3301 3310 3649 3759 14263 15370 15484 15667 15671 15683 15703 21643 22860 28892 29463 42407https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/123/2597?format=asciiInfrareddefaultJ/AJ/123/2597/table4Bright-Rimmed Clouds observedBRCBRC namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
