cds-question@unistra.frlate-type-starsproper-motionsphotometryeffective-temperaturestellar-massesstellar-agesWe present the results of a search for new candidate members of the Chamaeleon I and II star forming regions based on proper motions and multiwavelength photometry. Kinematic candidate members are initially selected in an area of 3 degrees around each cloud on the basis of proper motions and colours using the UCAC4 catalogue. The SEDs of the objects are constructed using photometry retrieved from the Virtual Observatory and other resources, and fitted to models of stellar photospheres in order to derive effective temperatures, gravity values and luminosities. Masses and ages are estimated by comparison with theoretical evolutionary tracks in a Hertzprung-Russell diagram. Objects with ages <=20Myr are selected as probable members of the moving groups. The properties of our candidates are compared with those of the previously known members of the clouds.2013A&A...556A.144Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/556/A144CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)I/322 : UCAC4 Catalogue (Zacharias+, 2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)III/265 : RAVE 3rd data release (Siebert+, 2011)http://www.aavso.org/apass : APASS: the AAVSO Photometric All-Sky Surveyhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/556/A144https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/556/A144http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/556/A144https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/556/A144https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/556/A144http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/556/A144GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/556/A144/stars (Kinematical candidate members of ChaI and II: proper motions, photometry, and derived masses and ages)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/556/A144/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/556/A144/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/556/A144/stars?GETtext/xml+votable180.050000true171.0792917-79.86352780.005555555555555556Cone search capability for table J/A+A/556/A144/table8 (Physical parameters of ChaI and II members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/556/A144/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/556/A144/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/556/A144/table8?GETtext/xml+votable180.050000true161.658125-77.60097220.0055555555555555565/9239 9280 10283 6/36943 36945-36949 36951 36953 36955 36976-36977 36980 37124 37126 37128-37129 37131-37132 37134 37152 41099 41124 41126-41127 41146 41473 414798.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/556/A144?format=asciiOpticaldefaultJ/A+A/556/A144/starsKinematical candidate members of ChaI and II: proper motions, photometry, and derived masses and agesPAv[0/1] Bayesian probability of Avstat.fit.goodnessfloatrecnoRecord number assigned by the VizieR team.
