Scientific paper

Large-scale anti-cyclonic vortices, resulting from global baroclinic instabilities, are considered as possible pre-cursors of planet formation. To answer the question if these significant features in circumstellar disks can be indeed observed in the near future, we simulate ALMA observations of disks with large-scale vortices, based on hydrodynamically calculated disks and subsequent 3D radiative transfer simulations. We find that ALMA will be able to trace the theoretically predicted large-scale anti-cyclonic vortex and will therefore allow testing of existing models of this very early stage of planet formation in circumstellar disks.
