Incorporates radiation pressure into collisional and dynamical simulations

Enables comprehensive study of debris disc evolution

Abstract

The first attempt at developing a fully self-consistent code coupling dynamics and collisions to study debris discs (Kral, Thebault, Charnoz, 2013) is presented. So far, these two crucial mechanisms were studied separately, with N-body and statistical collisional codes respectively, because of stringent computational constraints. In particular, incorporating collisional effects (especially destructive collisions) into an N-body scheme was deemed an impossible task because of the exponential increase of particles it would imply. We present here a new model named LIDT-DD which is able to follow over long timescales the coupled evolution of dynamics (including radiation pressure) and collisions in a self-consistent way.
