Authors: Sebastiano Bernuzzi, Luca Baiotti, Giovanni Corvino, Roberto De Pietri, Alessandro Nagar Date: 16 Feb 2009 Abstract: We compare different gravitational-wave extraction methods used in three-dimensional nonlinear simulations against linear simulations of perturbations of spherical spacetimes with matter. We present results from fully general-relativistic simulations of a system composed by an oscillating and non-rotating star emitting gravitational radiation. Results about the onset of non-linear effects are also shown. |
