The study on behaviour of thin accretion disc affected byPoynting–Robertson effect

This study deals with the structure of a thin accretion disc under the influence of radiation pressure and Poynting-Roberson effect. The disc is approximated by inhomogeneous dust consisting of point-like particles in vicinity of a point-like source of radiation. We have developed code PR Trajectories which computes trajectories of millions of particles forming an accretion disc and provides a lot of informations about the accretion disc.
