Abstract: Most stars in our Galaxy form in stellar aggregates, which can become long-lived structures called open clusters (OCs). Along their dynamical evolution, their gradual depletion leave some imprints on their structure. In this work, we… read more here.

DOI: 10.1093/mnras/stad999
Abstract: Previous studies pointed out that many observed samples of short-period binaries display a cutoff period, Pcut, such that almost all binaries with periods shorter than Pcut have circular orbits. This feature is probably due to… read more here.

DOI: 10.1093/mnrasl/slac082
Abstract: Gaia Data Release 2 (DR2) revealed that the Milky Way contains significant indications of departures from equilibrium in the form of asymmetric features in the phase space density of stars in the Solar neighborhood. One… read more here.
