Dedekind-like Configurations in Relativity — •Norman Gürlebeck¹ and David Petroff² — ¹Institute of Theoretical Physics, Prague, Czech Republic — ²Theoretisch-Physikalisches Institut, Jena, Germany

Because a changing quadrupole moment leads to gravitational radiation in Einstein's theory of gravity, one might suppose that stationary but non-static and non-axisymmetric, isolated systems cannot exist. In Newtonian theory, the triaxial, homogeneous Dedekind ellipsoids are classical figures of equilibrium whose shape remains unchanged in an inertial frame due to internal motions. In this talk, I shall discuss the possibility of using Dedekind ellipsoids as a basis for finding non-axisymmetric figures of equilibrium in General Relativity.
