Research: Multidimensional radiative transfer in protostellar disks
The inner gaseous regions of protoplanetary disks are of special interest in the formation and evolution of planets and stars. The study of such disks may give rise to a better understanding of the dynamics, physical and chemical structure, and gas content of this region. As a first step, we have developed a 1D disk radiative transfer package as an extension to the well established multi-purpose stellar atmosphere program PHOENIX. The goal of this work is to calculate 3D radiative transfer and investigate the effects of these more realistic simulations. Comparison of these detailed models with high-resolution spectra will enable us to constrain the structure and composition of disks, and thus provide a new insight into the processes governing star and planet formation.
