Abstract
The majority of stars form in a clustered environment. This has an impact on
the evolution of surrounding protoplanetary discs (PPDs) due to either
photoevaporation or tidal truncation. Consequently, the development of planets
depends on formation environment. Here we present the first thorough
investigation of tidally induced angular momentum loss in PPDs in the distant
regime, partly motivated by claims in the literature for the importance of
distant encounters in disc evolution. We employ both theoretical predictions
and dynamical/hydrodynamical simulations in 2D and 3D. Our theoretical analysis
is based on that of Ostriker (1994) and leads us to conclude that in the limit
that the closest approach distance
