Rapidly rotating neutron stars in Einstein-Gauss-Bonnet-dilaton theoryBurkhard Kleihaus, Jutta Kunz, and •Sindy Mojica — University of Oldenburg

Compact astrophysical objects like neutron stars are good natural laboratories for testing general relativity. Here we consider neutron stars in Einstein-Gauss-Bonnet-dilaton theory, which is a generalized model of gravity, motivated by String Theory. Similar to studies of black holes in this theory, our goal is to identify observable corrections to the properties of neutron stars. We here present our results for rapidly rotating neutron stars, and discuss the dependence of obervables like mass, angular momentum, moment of inertia and energy density on the angular velocity. We find that the mass and energy density decrease in Einstein-Gauss-Bonnet-dilaton theory.
