Accretion disks in space-times of compact objects with mass quadrupole

Compact massive objects like neutron stars always rotate. This leads to a deformation of the massive compact object which results in axially symmetric mass multipoles. The gravitational field of such a compact object gives a space-time different from known Black Hole space-times like the Kerr space-times. We describe thick and thin accretion disks in such axially symmetric space-times and discuss the modifications compared to accretion disks around Black Holes.
