Hydrodynamic modeling of accretion shocks on a star with radiative transport and a chromospheric model

de Sá, Lionel Chièze, Jean-Pierre Stehlé, Chantal

The aim of the project (ANR STARSHOCK) is to understand the dynamics and the radiative properties of accretion columns, linking the circumstellar disk to the surface photosphere of Young Stellar Objects. The hydrodynamics is computed first, using a high resolution hydrodynamic 1D ALE code (AS-TROLABE) coupled to radiative transfer and line...

New insight on Young Stellar Objects accretion shocks - a claim for NLTE opacities -

de Sá, Lionel Chièze, Jean-Pierre Stéhlé, Chantal

Context. Accreted material onto CTTSs is expected to form a hot plasma structure that radiates in X-rays. Simulations of this phenomenon only partly match with observations. They all rely on the assumption that radiation and matter are decoupled, and use in addition a static model for the chromosphere.Aims. We test the validity of these two...
