Neutron star data

Hyperboloidal initial data for neutron stars

As preparation for exciting simulations including matter on hyperboloidal slices, initial data including a neutron star first need to be developed. First results use constant-mean-curvature hyperboloidal slices.

Hyperboloidal slices including neutron stars. On the left, slices of a single polytropic-like neutron star in blue (surface in dashed back) and comparison to Minkowski in black. On the right, a neutron star with black hole at its center.
