cds-question@unistra.fropen-star-clustersccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe present UBVIc CCD photometry of the young open cluster Stock 8 with the aim of studying its basic properties such as the amount of interstellar extinction, distance, age, stellar contents and initial mass function (IMF). We also studied the star formation scenario in this region. From optical data, the radius of the cluster is found to be ~6arcmin (~3.6pc) and the reddening within the cluster region varies from E(B-V)=0.40 to 0.60mag. The cluster is located at a distance of 2.05+/-0.10kpc. Using H{alpha} slitless spectroscopy and Two Micron All Sky Survey (2MASS) near-infrared (NIR) data we identified H{alpha} emission and NIR-excess young stellar objects (YSOs), respectively.2008MNRAS.384.1675Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/384/1675CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/384/1675https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/384/1675http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/384/1675https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/384/1675https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/384/1675http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/384/1675GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/384/1675/table2 (UBVIc CCD photometry in Stock 8)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/384/1675/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/384/1675/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/384/1675/table2?GETtext/xml+votable180.050000true81.951291734.35738890.005555555555555556Cone search capability for table J/MNRAS/384/1675/table4 (Detected H{alpha} emission stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/384/1675/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/384/1675/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/384/1675/table4?GETtext/xml+votable180.050000true82.01937534.36416670.005555555555555556Cone search capability for table J/MNRAS/384/1675/table6 (List of OB stars in IC417 region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/384/1675/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/384/1675/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/384/1675/table6?GETtext/xml+votable180.050000true82.0291734.424170.0055555555555555566/1297 1299https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/384/1675?format=asciiOpticalInfrareddefaultJ/MNRAS/384/1675/table2UBVIc CCD photometry in Stock 8B-V?
