Post-Newtonian methods: Analytic results on the binary problem
Gerhard Schäfer
A detailed account is given on approximation schemes to the Einstein theory of general relativity where the iteration starts from the Newton theory of gravity. Two different coordi…
Binary Black Hole Coalescence in Semi-Analytic Puncture Evolution
Achamveedu Gopakumar, Gerhard Schaefer
Binary black-hole coalescence is treated semi-analytically by a novel approach. Our prescription employs the conservative Skeleton Hamiltonian that describes orbiting Brill-Lindqui…
Post-Newtonian Approximations, Compact Binaries, and Strong-Field Tests of Gravity
Luc Blanchet, L P Grishchuk, Gerhard Schaefer
This is an extended summary of the two parallel sessions held at MG11: PPN1 ``Strong Gravity and Binaries'' (chaired by L.B. and L.G.) and PPN2 ``Post-Newtonian Dynamics in Binary…
A skeleton approximate solution of the Einstein field equations for multiple black-hole systems
G. Faye, P. Jaranowski, G. Schaefer
An approximate analytical and non-linear solution of the Einstein field equations is derived for a system of multiple non-rotating black holes. The associated space-time has the sa…
Optimizing the third-and-a-half post-Newtonian gravitational radiation-reaction force for numerical simulations
Guillaume Faye, Gerhard Schaefer
The gravitational radiation-reaction force acting on perfect fluids at 3.5 post-Newtonian order is cast into a form which is directly applicable to numerical simulations. Extensive…
Can Schwarzschildean gravitational fields suppress gravitational waves?
Edward Malec, Gerhard Schaefer
Gravitational waves in the linear approximation propagate in the Schwarzschild spacetime similarly as electromagnetic waves. A fraction of the radiation scatters off the curvature…
