The study of star formation is extremely challenging due to the lack of complete and low-contaminated samples of young, nearby, clusters and star forming regions. We aim at providing a membership analysis with a high completeness and low contamination of the young, nearby, open cluster IC4665. We apply modern Bayesian statistical tools to the recent Gaia DR2 catalogue to identify high probability members. We find a list of 543 members of IC4665 with membership probabilities >87%, 251 of which are new members. We compute the magnitude distribution of these sample which peaks at G˜10, equivalent to ˜0.25 M_⊙.
