cds-question@unistra.fropen-star-clustersphotometryradial-velocityline-intensitiesThe so-called lithium depletion boundary (LDB) provides a secure and independent tool for deriving the ages of young open clusters. In this context, our goal is to determine membership for a sample of 147 photometrically selected candidates of the young open cluster IC 4665 and to use confirmed members to establish an age based on the LDB. Employing the FLAMES multi-object spectrograph on VLT/UT2, we have obtained intermediate-resolution spectra of the cluster candidates. The spectra were used to measure radial velocities and to infer the presence of the LiI 670.8nm doublet and H{alpha} emission.2008A&A...479..141Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/479/141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/105/1441 : IC 4665 photometry and proper motions (Prosser 1993)J/A+A/448/189 : IzJHK photometry of IC4665 (de Wit+, 2006)J/A+A/475/539 : BV photometry and Li abundances in NGC 3960 (Prisinzano+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/479/141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/479/141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/479/141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/479/141https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/479/141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/479/141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/479/141/table1 (The 147 candidate members of IC 4665 observed with FLAMES)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/479/141/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/479/141/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/479/141/table1?GETtext/xml+votable180.050000true266.18756256.036513890.0055555555555555566/31788 31790https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/479/141?format=asciiOpticaldefaultJ/A+A/479/141/table1The 147 candidate members of IC 4665 observed with FLAMESrecnoRecord number assigned by the VizieR team.
