Abstract

Context. The external destruction of protoplanetary discs in a clustered environment acts mainly due to two mechanisms: gravitational drag by stellar encounters and evaporation by strong stellar winds and radiation. It is a fundamental question whether either of these mechanisms is important for the stellar evolution and planet formation process in young star clusters.
