cds-question@unistra.frstellar-evolutionary-modelspre-main-sequence-starsRotational evolution in young stars is described by pre-main sequence evolutionary tracks including non-gray boundary conditions, rotation, conservation of angular momentum, and simulations of disk-locking. By assuming that disk-locking is the regulation mechanism for the stellar angular velocity during the early stages of pre-main sequence evolution, we use our rotating models and observational data to constrain disk lifetimes (Tdisk) of a representative sample of low-mass stars in two young clusters, the Orion Nebula cluster (ONC) and NGC 2264, and to better understand their rotational evolution. The period distributions of the ONC and NGC 2264 are known to be bimodal and to depend on the stellar mass. To follow the rotational evolution of these two clusters' stars, we generated sets of evolutionary tracks from a fully convective configuration with low central temperatures (before D- and Li-burning). We assumed that the evolution of fast rotators can be represented by models considering conservation of angular momentum during all stages and of moderate rotators by models considering conservation of angular velocity during the first stages of evolution. With these models we estimate a mass and an age for all stars.2016A&A...586A..96Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/586/A96CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/496/223 : PMS tracks at low Z for 0.1<=M<=1.5 (Di Criscienzo+, 2009)J/A+A/510/A46 : Pre-main sequence evolutionary tracks (Landin+, 2010)J/A+A/533/A109 : Pisa pre-main sequence tracks and isochrones (Tognelli+, 2011)J/A+A/541/A113 : Evolutionary tracks for pre-main sequence stars (Claret, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/586/A96https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/586/A96http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/586/A96https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/586/A96https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/586/A96http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/586/A96GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/586/A96/table1eDisk-locking models (Plock=8d Tdisk=1Myr)recnoRecord number assigned by the VizieR team.
