A characteristic approach to the quasi-normal mode problem
Lars Samuelsson, Nils Andersson, Asimina Maniopoulou
In this paper we discuss a new approach to the quasinormal-mode problem in general relativity. By combining a characteristic formulation of the perturbation equations with the inte…
Rotating neutron stars: an invariant comparison of approximate and numerical spacetime models
Emanuele Berti, Frances White, Asimina Maniopoulou +1
We compare three different models of rotating neutron star spacetimes: the Hartle-Thorne (HT) slow-rotation approximation at second order in rotation, the exact analytic vacuum sol…
The traditional approximation in general relativity
Asimina Maniopoulou, Nils Andersson
We discuss the generalisation of the so-called traditional approximation, well known in geophysics, to general relativity. We show that the approximation is applicable for rotating…
