Detailed Description

This module generates the inspiral waveform from a binary consisting of two spinning compact stars.

Author: Sathyaprakash, B. S.

Prototypes

LALInspiralSpinningBHBinary()

signalvec: Output containing the spin modulated inspiral waveform.
in: Input containing binary chirp parameters.

Description

Using the formalism described in Apostolatos et al [2] and Blanchet et al. [5] and formulas summarized in Sec. Spinning Modulated Chirps this module computes the spin-modulated chirps from a pair of compact stars in orbit around each other.

Algorithm

This code uses a fourth-order Runge-Kutta algorithm to solve the nine first-order, coupled, ordinary differential equations in Eq. \eqref{eqn_precession1} Eq. \eqref{eqn_precession2} and Eq. \eqref{eqn_precession3}. The solution is then used in Eq. \eqref{eqn_waveform} (and following equations) to get the waveform emitted by a spinning black hole binary.

Uses

LALInspiralSetup()
LALInspiralChooseModel()
LALInspiralVelocity()
LALInspiralPhasing3()
LALRungeKutta4()
