Spin and Quadrupole Contributions to the Motion of Astrophysical Binaries

Compact objects in general relativity approximately move along geodesics of spacetime. It is shown that the corrections to geodesic motion due to spin (dipole), quadrupole, and higher multipoles can be modeled by an extension of the point mass action. The

Preface

The derivation of the equations of motion for extended bodies represents a fundamental problem in relativistic gravitational physics. Since the early days of Einstein’s theory of General Relativity, a wide spectrum of methods has been proposed to allow for the derivation in different physical settings. Without having such equations of motion at hand it is impossible to correctly describe, for example, the motion of binary systems, or to calculate the form of gravitational waves emitted by such systems. These equations are also crucial for astrometry and for high precision satellite missions. In 2013 we organized1 an international conference in Bad Honnef (Germany) o
