In this study, we explore the near-IR properties of optically identified classical Be stars in 19 star clusters in the Magellanic Clouds. From an optically identified sample of 835 Be stars we obtained the J, H, K magnitudes of 389 stars from the IRSF MCPS catalog. Among these, 247 stars (36.4%) are found in 9 clusters in the Large Magellanic Cloud and 142 stars (55.5%) in 10 clusters in the Small Magellanic Cloud. After correcting for reddening, we studied their NIR properties in the (H-K)_0_ vs (J-H)_0_ diagram. We identified 14 stars with abnormally large near IR excesses, which were removed from the analysis, there by restricting our study to 355 classical Be stars. We propose an extended area in the near-IR (H-K)_0_ vs (J-H)_0_ diagram as the diagnostic location of Classical Be stars in the Magellanic Clouds. We identified 14 stars to have near-IR excess, higher than those seen in classical Be stars. From the analysis based on spectral energy distribution and luminosity estimate, we found that 8 candidate Be stars may be Herbig Ae/Be stars. We identified a new sample of 6 sgB[e] stars, which when added to the sparse existing sample of 15 sgB[e] stars in the Magellanic Clouds can provide insight to understand the evolutionary link between sgB[e] stars and Luminous Blue variables.2017NewA...56...28Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NewA/56.28CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/288 : IRSF Magellanic Clouds Point Source Catalog (Kato+ 2007)J/A+AS/134/489 : Be stars in MC young clusters (Keller+ 1999)J/ApJ/652/458 : Candidates Be stars BVRH{alpha} photometry (Wisniewski+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NewA/56.28https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NewA/56.28http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NewA/56.28https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NewA/56.28https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NewA/56.28http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NewA/56.28GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NewA/56.28/table5 (Optical and NIR photometric magnitudes of Be candidate stars identified in the LMC and SMC clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/56.28/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/56.28/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/56.28/table5?GETtext/xml+votable180.050000true12.9282917-73.22431940.005555555555555556Cone search capability for table J/other/NewA/56.28/table6 (Optical and NIR photometric magnitudes of Be candidate stars identified in the LMC and SMC clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/56.28/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/56.28/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/56.28/table6?GETtext/xml+votable180.050000true14.0277083-72.46010560.0055555555555555566/33094 33098 33101 33112 33113 33115 33120 33124 33125 33127 33295 33298 33304 33307 33317 333287.952274030004205e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NewA/56.28?format=asciiInfraredOpticaldefaultJ/other/NewA/56.28/table5Optical and NIR photometric magnitudes of Be candidate stars identified in the LMC and SMC clusterse_Jmagrms uncertainty on Jmagmagstat.error;phot.mag;em.IR.JfloatrecnoRecord number assigned by the VizieR team.
