Observability of characteristic binary-induced structures in circumbinary disks

A substantial fraction of protoplanetary disks form around stellar binaries. The properties of these circumbinary disks are currently a topic of very active research. In this paper, the authors study the strong tidal forces that act on the circumbinary disk as a consequence of the non-axisymmetric gravitational potential generated by the binary system. They aim to identify structures characteristic of the binarity and to evaluate the feasibility of observing them with current and future instruments. To do this, they perform 2D hydrodynamic simulations and post-process the resulting density distributions with a 3D radiative tran/per t">
