A one-dimensional, hydrostatic, plane-parallel and spherical LTE model atmospheres. MARCS has been applied to oxygen-rich and carbon-rich AGB stars, M-dwarfs, White-dwarfs and lately also to Brown Dwarfs and young, giant exoplanets.
ProDiMo (PROtoplanetary DIsk MOdel) is a scientific software package in FORTRAN 90 to model protoplanetary disks including gas phase, X-ray and UV-photo-chemistry, gas heating and cooling balance, disk structure and (dust & line) radiative transfer. ProDiMo is available on a collaborative basis.

The ARCiS framework for exoplanet modelling and retrieval is under development and will be presented in a sequence of papers. The guiding philosophy behind the approach is to provide a framework where we can optimally combine theory and observations to extract knowledge and learn about the processes in exoplanet atmospheres.
