Short description of the thesis

Gaseous disks influence the formation and evolution of binary systems. Circumbinary disks produce periodic electromagnetic signatures, caused by the precession of an eccentric disk. This thesis shows how differences in binary and disk properties, such as the binary mass ratio and eccentricity, or disk size and mass, change the expected values for the disk precession frequency and the radial eccentricity distribution in the disk. Thus, the results are easily applicable to a wide range of binary-disk systems, from protoplanetary disks to disks surrounding supermassive black hole binaries.
