cds-question@unistra.frstellar-associationsyoung-stellar-objectspre-main-sequence-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present the analysis of the stellar content of NGC 2282, a young cluster in the Monoceros constellation, using deep optical BVI and INT Photometric H{alpha} Survey (IPHAS) photometry along with infrared (IR) data from UKIRT Infrared Deep Sky Survey and Spitzer-IRAC. Based on the stellar surface density analysis using nearest neighbourhood method, the radius of the cluster is estimated as ~3.15-arcmin. From optical spectroscopic analysis of eight bright sources, we have classified three early B-type members in the cluster, which includes, HD 289120, a previously known B2V-type star, a Herbig Ae/Be star (B0.5 Ve) and a B5 V star. From spectrophotometric analyses, the distance to the cluster has been estimated as ~1.65kpc. The K-band extinction map is estimated using nearest neighbourhood technique, and the mean extinction within the cluster area is found to be A_V_~3.9mag. Using IR colour-colour criteria and H{alpha}-emission properties, we have identified a total of 152 candidate young stellar objects (YSOs) in the region, of which, 75 are classified as Class II, nine are Class I YSOs. Our YSO catalogue also includes 50 H{alpha}-emission line sources, identified using slitless spectroscopy and IPHAS photometry data. Based on the optical and near-IR colour-magnitude diagram analyses, the cluster age has been estimated to be in the range of 2-5Myr, which is in agreement with the estimated age from disc fraction (~58 per cent). Masses of these YSOs are found to be ~0.1-2.0M_{sun}_. Spatial distribution of the candidate YSOs shows spherical morphology, more or less similar to the surface density map.2015MNRAS.454.3597Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/454/3597CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/113/1788 : Near-IR Imaging Survey of NGC 2282 (Horner+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/454/3597https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/454/3597http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/454/3597https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/454/3597https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/454/3597http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/454/3597GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/454/3597/table2 (Multi-wavelength catalog of NGC 2282)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/3597/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/3597/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/3597/table2?GETtext/xml+votable180.050000true101.7096181.2765340.005555555555555556Cone search capability for table J/MNRAS/454/3597/table3 (Details of the spectroscopically studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/3597/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/3597/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/3597/table3?GETtext/xml+votable180.050000true101.70961.276640.005555555555555556Cone search capability for table J/MNRAS/454/3597/table4 (Catalog of YSOs (Class I, Class II, other PMS stars and H{alpha} sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/3597/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/3597/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/3597/table4?GETtext/xml+votable180.050000true101.7230241.31040.0055555555555555566/222094.414320678087048e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/454/3597?format=asciiOpticalInfrareddefaultJ/MNRAS/454/3597/table2Multi-wavelength catalog of NGC 2282DEJ2000Declination (J2000)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
