cds-question@unistra.frmagellanic-cloudspre-main-sequence-starsinfrared-photometryWe have found Herbig Ae/Be star candidates in the western region of the Magellanic Bridge. Using the near-infrared camera SIRIUS and the 1.4m telescope IRSF, we surveyed ~3.0{deg}x1.3{deg} (24{deg}<~RA<~36{deg}, -75.0{deg}<~DE<~-73.7{deg}) in the J, H, and Ks bands. On the basis of colors and magnitudes, about 200 Herbig Ae/Be star candidates are selected. Considering the contaminations by miscellaneous sources, such as foreground stars and early-type dwarfs in the Magellanic Bridge, we estimate that about 80 (#40%) of the candidates are likely to be Herbig Ae/Be stars. We also found one concentration of the candidates at the young star cluster NGC 796, strongly suggesting the existence of pre-main-sequence (PMS) stars in the Magellanic Bridge. This is the first detection of PMS star candidates in the Magellanic Bridge, and if they are genuine PMS stars, this could be direct evidence of recent star formation. However, the estimate of the number of Herbig Ae/Be stars depends on the fraction of classical Be stars, and thus a more precise determination of the Be star fraction or observations to differentiate between the Herbig Ae/Be stars and classical Be stars are required.2007ApJ...658..358Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/658/358CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/PASAu/6.471 : Magellanic Clouds bridge region HI profiles (McGee+ 1986)J/ApJS/101/41 : SMC and Bridge extended catalog (Bica+ 1995)J/MNRAS/339/105 : Western Magellanic Bridge HI observations (Muller+, 2003)J/ApJ/658/345 : CRIc photometry of Magellanic Bridge Fields (Harris 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/658/358https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/658/358http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/658/358https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/658/358https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/658/358http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/658/358GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/658/358/table1 (Catalog of Herbig Ae/Be star candidates in the Magellanic Bridge)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/658/358/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/658/358/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/658/358/table1?GETtext/xml+votable180.050000true24.4515417-73.79505560.0055555555555555565/8239 6/32949 32950 32951 32953 32955 32994 33000 33300https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/658/358?format=asciiInfrareddefaultJ/ApJ/658/358/table1Catalog of Herbig Ae/Be star candidates in the Magellanic Bridge[NHK2007]Sequential numbermeta.recordintrecnoRecord number assigned by the VizieR team.
