Ineffectiveness of Padé resummation techniques in post-Newtonian approximations
Abdul H. Mroué, Lawrence E. Kidder, Saul A. Teukolsky
We test the resummation techniques used in developing Padé and Effective One Body (EOB) waveforms for gravitational wave detection. Convergence tests show that Padé approximants of…
Initial data for black hole-neutron star binaries: a flexible, high-accuracy spectral method
Francois Foucart, Lawrence E. Kidder, Harald P. Pfeiffer +1
We present a new numerical scheme to solve the initial value problem for black hole-neutron star binaries. This method takes advantage of the flexibility and fast convergence of a…
High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles
Manuel Tiglio, Lawrence Kidder, Saul Teukolsky
We investigate the late time behavior of a scalar field on a fixed Kerr background using a 2+1 dimensional pseudospectral evolution code. We compare evolutions of pure axisymmetric…
An Efficient Method for Fully Relativistic Simulations of Coalescing Binary Neutron Stars
Walter Landry, Saul A. Teukolsky
The merger of two neutron stars has been proposed as a source of gamma-ray bursts, r-process elements, and detectable gravitational waves. Extracting information from observations…
Hot, Rotating Disks In General Relativity: Collisionless Equilibrium Models
A. Katrin Schenk, Stuart L. Shapiro, Saul A. Teukolsky
We present a method for constructing equilibrium disks with net angular momentum in general relativity. The method solves the relativistic Vlasov equation coupled to Einstein's equ…
Binary Neutron Stars in Quasi-Equilibrium Circular Orbit: A Fully Relativistic Treatment
Thomas W. Baumgarte, Stuart L. Shapiro, Gregory B. Cook +2
We present a numerical scheme that solves the initial value problem in full general relativity for a binary neutron star in quasi-equilibrium. While Newtonian gravity allows for a…
