Solar twins in M 67: evolutionary status and lithium abundance
Aims. We determine the age and mass of the three best solar twin candidates in open cluster M 67 through lithium evolutionary models. Methods. We computed a grid of evolutionary models with non-standard mixing at metallicity [Fe/H] = 0.01 with the ToulouseGeneva evolution code for a range of stellar...
