cds-question@unistra.frstellar-associationsyoung-stellar-objectsinfrared-photometryBright-rimmed clouds (BRCs), illuminated and shaped by nearby OB stars, are potential sites of recent/ongoing star formation. Here we present an optical and infrared photometric study of three BRCs: BRC 5, BRC 7 and BRC 39 to obtain a census of the young stellar population, thereby inferring the star formation scenario, in these regions. In each BRC, the Class I sources are found to be located mostly near the bright rim or inside the cloud, whereas the Class II sources are preferentially outside, with younger sources closer to the rim. This provides strong support to sequential star formation triggered by radiation-driven implosion due to the ultraviolet radiation. Moreover, each BRC contains a small group of young stars being revealed at its head, as the next-generation stars. In particular, the young stars at the heads of BRC 5 and BRC 7 are found to be intermediate-/high-mass stars, which, under proper conditions, may themselves trigger further star birth, thereby propagating star formation out to long distances.2014MNRAS.443.1614Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/443/1614CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/123/2597 : H{alpha} stars and HH objects near BRCs (Ogura+, 2002)J/AJ/143/61 : H{alpha} spectroscopy in IC 1396 HII region (Nakano+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/443/1614https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/443/1614http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/443/1614https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/443/1614https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/443/1614http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/443/1614GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/443/1614/table2 (2MASS, IRAC and WISE photometry of the identified YSOs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/1614/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/1614/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/1614/table2?GETtext/xml+votable180.050000true36.9789561.548220.005555555555555556Cone search capability for table J/MNRAS/443/1614/table3 (Magnitudes and age/mass of the YSOs in the BRC regions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/1614/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/1614/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/1614/table3?GETtext/xml+votable180.050000true37.0526261.570010.0055555555555555566/3307 3310 3649 154778.157980699529898e-21 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/443/1614?format=asciiInfrareddefaultJ/MNRAS/443/1614/table22MASS, IRAC and WISE photometry of the identified YSOsYSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
