Abstract

Despite intense observational work, the stellar accretion process is insufficiently constrained, and consequently the details in the exchange of mass and momentum between the proto-star and its accretion disk remain approximate. We focus here on 1D simulations of accretion columns falling onto a stellar chromosphere. After the description of the method used for the radiative hydrodynamics, we first describe the mutual feedback between a dynamically heated chromosphere and the accretion process and the coupling between radiation and matter. Perspectives to this work will finally be presented.
