cds-question@unistra.fropen-star-clustersastrometryphotometryRuprecht 147 is the oldest (2.5Gyr) open cluster in the solar vicinity (<300pc), making it an important target for stellar evolution studies and exoplanet searches. We aim to derive a census of members and the luminosity, mass, and spatial distributions of the cluster. We used an astro-photometric data set including all available information from the literature together with our own observations. We processed the data with an updated version of an existent membership selection methodology. We identify 259 high-probability candidate members, including 58 previously unreported. All these candidates cover the luminosity interval between G>6mag to i<21mag. The cluster luminosity and mass distributions are derived with an unprecedented level of details allowing us to recognize, among other features, the Wielen dip. The mass distribution in the low-mass regime drops sharply at 0.4M_{sun}_ even though our data are sensitive to stellar masses down to 0.1M_{sun}_, suggesting that most very-low-mass members left the cluster as the result of its dynamical evolution. In addition, the cluster is highly elongated (ellipticity~0.5) towards the galactic plane, and mass segregated. Our combined Gaia+DANCe data set allows us to obtain an extended list of cluster candidate members, and to derive luminosity, mass, and projected spatial distributions in the oldest open cluster of the solar vicinity.2019A&A...625A.115Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/625/A115CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/625/A115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/625/A115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/625/A115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/625/A115https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/625/A115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/625/A115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/625/A115/table7 (DANCe astrometry, photometry and membership probabilities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/625/A115/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/625/A115/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/625/A115/table7?GETtext/xml+votable180.050000true292.996131988-19.02986106050.005555555555555556Cone search capability for table J/A+A/625/A115/table9 (Cluster candidate members: id, astrometry, photometry, membership probability)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/625/A115/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/625/A115/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/625/A115/table9?GETtext/xml+votable180.050000true286.577835918-13.80082978750.0055555555555555564/1815 1858 5/7253-7255 7257 7285 7424 7426-7427 6/28998 29003 29005 29007 29011 29037 29137 29144 29149 29701-29702 29722 29744-29746 29754-29755 29824-29826 29830 29841-29842 48123 48127 488108.650015785639275e-20 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/625/A115?format=asciidefaultJ/A+A/625/A115/table6Gaia DR2 ids and membership probabilitiesrecnoRecord number assigned by the VizieR team.
