Rapidly rotating neutron stars in Einstein-Gauss-Bonnet dilaton theory — •Sindy Mojica1, Burkhard Kleihaus1, Jutta Kunz1, and Marco Zagermann21University of Oldenburg — 2University of Hannover

Motivated by string theory, we studied neutron stars in Einstein Gauss Bonnet dilaton theory (EGBD). Neutron stars are considered as laboratories to test general relativity and theories beyond. We calculated observables such that: mass, angular momentum, moment of inertia and quadrupole moment for rapidly rotating neutron stars in EGBD gravity.

In order to determine the dependence on neutron stars matter constituents and the coupling parameter from the EGBD approximation, we have proven that universal relations for neutron stars may exist in EGBD theory, when the angular momentum is fixed and the moment of inertia and quadrupole moment are scaled.
