A new approach to helical Killing vectors — •Hannes Rüter — Potsdam, Germany

Helical Killing Vectors are an important ingredient for the description of binary systems in quasi-equilibrium, which makes them one of the central quantities in the construction of numerical-relativity initial data of compact binaries. Current approaches to helical Killing vectors and their generalisations to eccentric orbits are defined in a foliation-dependent manner. In this presentation I will a discuss a new approach that attempts to break this foliation dependence.
