Abstract

We present our code for the calculation of the ID structure and synthetic spectra of accretion disks. The code is an extension of the well-tested stellar atmosphere code PHOENIX and is therefore capable of including large lists of atomic and molecular lines as well as a large set of dust species. We assume the standard accretion disk model for geometrically thin disks and solve the radiative transfer equation in the vertical direction for a number of disk rings with different radii. The combination of these rings yields the total disk spectrum. Comparison to observations of the T Tauri star GQ Lup shows the capability of our code. Additionally, we will show first results of 3D radiative transfer calculations. We plan to investigate the effect of rotating disks on the line profile by means of a two-level atom.
