Observables of a test-mass along an inclined orbit in a post-Newtonian approximated Kerr spacetime to leading-order-quadratic-in-spin
Steven Hergt, Abhay Shah, Gerhard Schäfer
The orbital motion is derived for a non-spinning test-mass in the relativistic, gravitational field of a rotationally deformed body not restricted to the equatorial plane or spheri…
On the comparison of results regarding the post-Newtonian approximate treatment of the dynamics of extended spinning compact binaries
Steven Hergt, Jan Steinhoff, Gerhard Schaefer
A brief review is given of all the Hamiltonians and effective potentials calculated hitherto covering the post-Newtonian (pN) dynamics of a two body system. A method is presented t…
Elimination of the spin supplementary condition in the effective field theory approach to the post-Newtonian approximation
Steven Hergt, Jan Steinhoff, Gerhard Schaefer
The present paper addresses open questions regarding the handling of the spin supplementary condition within the effective field theory approach to the post-Newtonian approximation…
ADM canonical formulation with spin and application to post-Newtonian approximations
J. Steinhoff, S. Hergt, G. Schäfer
Recently, different methods succeeded in calculating the spin dynamics at higher orders in the post-Newtonian (PN) approximation. This is an essential step toward the determination…
Reduced Hamiltonian for next-to-leading order Spin-Squared Dynamics of General Compact Binaries
Steven Hergt, Jan Steinhoff, Gerhard Schaefer
Within the post Newtonian framework the fully reduced Hamiltonian (i.e., with eliminated spin supplementary condition) for the next-to-leading order spin-squared dynamics of genera…
Higher-order-in-spin interaction Hamiltonians for binary black holes from Poincaré invariance
Steven Hergt, Gerhard Schäfer
The fulfillment of the space-asymptotic Poincaré algebra is used to derive new higher-order-in-spin interaction Hamiltonians for binary black holes in the Arnowitt-Deser-Misner can…
