cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomyWide-band photometryccd-photometryWe have carried out deep (V~21mag) UBVRI photometric study of the star cluster Stock 18. These along with archival Infrared data have been used to derive the basic cluster parameters and also to derive the basic cluster parameters and also to study the star for formation processes in and around the cluster region. The distance to the cluster is derived as 2.8+/-0.2kpc while its age is estimated as 6.0+/-2.0Myr. Present study indicates that interstellar reddening is normal in the direction of the cluster. The mass function slope is found to be -1.37+/-0.27 for the mass range 1<M/M_{sun}_<11.9. There is no evidence found for the effect of mass segregation in main-sequence stars of the cluster. A young stellar population with age between 1-2Myr have been found in and around the cluster region. The presence of IRAS and AKARI sources with MSX intensity map also show the youth of the Sh2-170 region.2012NewA...17..160Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NewA/17.160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NewA/17.160https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NewA/17.160http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NewA/17.160https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NewA/17.160https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NewA/17.160http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NewA/17.160GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NewA/17.160/table2 (*UBVRI photometric data of the sample stars in 13'x13' region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/17.160/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/17.160/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/17.160/table2?GETtext/xml+votable180.050000true0.3884438964.512168890.0055555555555555566/30672.263356695087955e-19 6.298619151247743e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NewA/17.160?format=asciiOpticalInfrareddefaultJ/other/NewA/17.160/table2*UBVRI photometric data of the sample stars in 13'x13' regionrecnoRecord number assigned by the VizieR team.
