dc.description.abstractEnIC 4665 is one of the few well-known, young (30 Myr), open clusters in the solar neighbourhood. The relatively young age of this cluster provides a key anchor to study the stellar and planetary formation process. In addition it is a good target where to test evolutionary models. We aim to provide a comprehensive membership analysis of this open cluster which allows to study its properties (empirical isochrones, luminosity and mass functions, spatial distribution). We combine the Gaia DR2 catalogue together with the deep, ground based COSMIC DANCe catalogue to compute membership probabilities. We find 819 candidate members of IC 4665 with high membership probabilities, 50% of which are new members, and we estimate that 20% might be contaminants. This represents a signicant increase in the quantity and quality (higher completeness and low-contamination) with respect to previous studies. Our members include objects of sub-stellar masses which we will spectroscopically follow-up in order to do a spectral classication and search for possible companions.
