cds-question@unistra.frmilky-way-galaxyopen-star-clustersstellar-associationsWe report the serendipitous discovery of three new open clusters, named UFMG 1, UFMG 2 and UFMG 3 in the field of the intermediate-age cluster NGC 5999, by using Gaia DR2 data. A colour-magnitude filter tailored for a proper selection of main-sequence stars and red clump giants turned evident the presence of NGC 5999 and these three new stellar groups in proper motion space. Their structural parameters were derived from King-profile fittings over their projected stellar distributions and isochrone fits were performed on the clusters cleaned colour-magnitude diagrams built with Gaia bands to derive their astrophysical parameters. The clusters projected sky motion were calculated for each target using our members selection. Distances to the clusters were inferred from stellar parallaxes through a bayesian model, showing that they are marginally consistent with their isochronal distances , considering the random and systematic uncertainties involved. The new clusters are located in the nearby Sagittarius arm (d~1.5kpc) with NGC 5999 at the background (d~1.8kpc). They contain at least a few hundred stars of nearly solar metallicity and have ages between 100 and 1400Myr.2019MNRAS.483.5508Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/5508CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/5508https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/5508http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/5508https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/5508https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/5508http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/5508GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/5508/table1 (Astrophysical parameters for the new clusters and NGC 5999)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5508/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5508/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5508/table1?GETtext/xml+votable180.050000true238.047083-56.4880560.005555555555555556Cone search capability for table J/MNRAS/483/5508/ngc5999 (NGC 5999 member list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5508/ngc5999?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5508/ngc5999?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5508/ngc5999?GETtext/xml+votable180.050000true238.04233-56.59853390.005555555555555556Cone search capability for table J/MNRAS/483/5508/ufmg1 (UFMG 1 member list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5508/ufmg1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5508/ufmg1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5508/ufmg1?GETtext/xml+votable180.050000true236.34772-56.96109390.005555555555555556Cone search capability for table J/MNRAS/483/5508/ufmg2 (UFMG 2 member list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5508/ufmg2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5508/ufmg2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5508/ufmg2?GETtext/xml+votable180.050000true237.64566-56.157120.005555555555555556Cone search capability for table J/MNRAS/483/5508/ufmg3 (UFMG 3 member list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5508/ufmg3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5508/ufmg3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5508/ufmg3?GETtext/xml+votable180.050000true238.25319-55.634750.0055555555555555566/41467 41797 41808-41809 418121.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/5508?format=asciidefaultJ/MNRAS/483/5508/table1Astrophysical parameters for the new clusters and NGC 5999RAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainGLONGalactic longitudedegpos.galactic.lonGLATGalactic latitudedegpos.galactic.latfloatpmRA*Proper motion along RA, pmRA*cosDEmas/yrpos.pm;pos.eq.rafloate_pmRA*rms uncertainty on pmRA* (1)uarcsec/yrstat.error;pos.pm;pos.eq.raintpmDEProper motion along DEmas/yrpos.pm;pos.eq.decfloate_pmDErmns uncertainty on pmDE (1)uarcsec/yrstat.error;pos.pm;pos.eq.decintrlimLimiting radius, defined as the radius where the stellar density reaches the sky levelpcphys.size.radiusfloate_rlimrms uncertainty on rlimpcstat.errorfloatrcCore radiuspcphys.size.radiusfloate_rcrms uncertainty on rcpcstat.errorfloatrtTital radiuspcphys.size.radiusfloate_rtrms uncertainty on rtpcstat.errorfloatlogtAgelog(yr)time.agefloate_logtrms uncertainty on logtlog(yr)stat.errorfloatm-MDistance modulusmagphot.mag.distModfloate_m-Mrms uncertainty on m-Mmagstat.errorfloatcContentration parameter (c=log(rt/rc))stat.fit.paramfloat[Fe/H]Metallicityphys.abund.Zfloate_[Fe/H]rms uncertainty on [Fe/H]stat.error;phys.abund.FefloatDistDistancekpcpos.distance;pos.heliocentricfloate_Distrms uncertainty on Distkpcstat.errorfloatE(B-V)Reddeningmagphot.color.excessfloate_E(B-V)rms uncertainty on E(B-V)magstat.errorfloatNNumber of membersmeta.numberintFileNameName of the file with member listmeta.filecharrecnoRecord number assigned by the VizieR team.
