cds-question@unistra.fropen-star-clustersinfrared-sourcesphotometryLittle is known about the population of the Coma Berenices open cluster (age~500Myr) below 0.2M_{sun}_, and statistics show that there is a prominent deficit of very low-mass objects in this mass range compared to younger open clusters with ages of <250Myr. We search for very low-mass stars and substellar objects (brown dwarfs) in the Coma open cluster to derive the present-day cluster mass function below 0.2M_{sun}_.2012A&A...544A.111Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/544/A111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/134/2340 : Membership of Praesepe and Coma Ber clusters (Kraus+, 2007)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)http://www.ukidss.org : UKIDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/544/A111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/544/A111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/544/A111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/544/A111https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/544/A111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/544/A111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/544/A111/tableb1 (RI and 2MASS JHKs photometry of Coma open cluster member candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/544/A111/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/544/A111/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/544/A111/tableb1?GETtext/xml+votable180.050000true184.46166723.8252780.0055555555555555565/7034 7120-7122 6/28093 28095 28131 28140 28142 28436-28437 28439 28492-28494 284988.650015785639275e-20 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/544/A111?format=asciiOpticalInfrareddefaultJ/A+A/544/A111/tableb1RI and 2MASS JHKs photometry of Coma open cluster member candidatesOName2MASS or UKIDSS namemeta.notecharrecnoRecord number assigned by the VizieR team.
