Self-gravitating neutron star-disks in general relativity

Binary neutron star mergers or accreting compact objects other than black holes can lead to a self-gravitating neutron star-disk system. Using the COCAL initial value code, we compute self-gravitating neutron star-disk spacetimes for a variety of neutron star equations of state and rotation parameters, as well as for different disk angular velocity profiles. We make direct comparisons with similar self-gravitating disks around black holes.
