cds-question@unistra.fropen-star-clustersearly-type-starsline-intensitiesWe have studied age dependent features in optical and near-infrared spectra of candidate members to the cluster (such as alkali lines and accretion associated indicators). In addition, we have complemented that study with the analysis of other youth indicators like X-ray emission or mid-infrared excess. We have confirmed the membership to Collinder 69 of ~90 photometric candidate members. As a byproduct we have determined a temperature scale for young M, very low-mass stars and brown dwarfs. We have assembled one of the most complete Initial Mass Functions from 0.016 to 20M_{sun}_. And, finally, we have studied the implications of the spatial distribution of the confirmed members on the proposed mechanisms of brown dwarfs formation.2011A&A...536A..63Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/536/A63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/118/2409 : VRI photometry of lambda Ori PMS stars (Dolan+, 1999)J/AJ/121/2124 : lambda Ori pre-main-sequence stars photometry (Dolan+, 2001)J/ApJ/610/1064 : lambda Ori substellar population (Barrado y Navascues+ 2004)J/ApJ/664/481 : Collinder 69 opt/IR photometry (Barrado y Navascues+ 2007)J/A+A/488/167 : Low-mass stars in sigma Ori and lambda Ori (Sacco+, 2008)J/A+A/492/277 : Analysis of Collinder 69 stars with VOSA (Bayo+, 2008)J/MNRAS/385/2210 : Spectroscopy around lam Ori and sig Ori (Maxted+, 2008)J/A+A/526/A21 : Collinder 69 X-ray sources (Barrado+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/536/A63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/536/A63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/536/A63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/536/A63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/536/A63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/536/A63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/536/A63/table6 (Summary of the parameters derived in this work for Collinder 69 candidate members and comparison with previous studies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/536/A63/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/536/A63/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/536/A63/table6?GETtext/xml+votable180.050000true83.446589.927360.0055555555555555566/23717 23719 23728https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/536/A63?format=asciidefaultJ/A+A/536/A63/table6Summary of the parameters derived in this work for Collinder 69 candidate members and comparison with previous studiesSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
