Neutron Stars
Neutron stars consist
of interpenetrating neutron and proton superfluids that drag
each other along as they move. The very high density and
strong gravitational fields in these stars mean that these
fluids must be described using Einsteinâ€™s general theory of
relativity. Greg Comer and I constructed a
Lorentzcovariant theory to describe this drag effect. This
makes possible accurate numerical simulations of these
stars.
