Brown dwarfs and very low mass stars in the Praesepe open cluster: a dynamically unevolved mass function?
Context. Determination of the mass functions of open clusters of different ages allows us to infer the efficiency with which brown dwarfs are evaporated from clusters to populate the field. Aims: In this paper we present the results of a photometric survey to identify low mass and brown dwarf members of the old open cluster Praesepe (age 590+150
