Gravitational waves and pulsating stars: What can we learn from future observations?
Nils Andersson, Kostas D. Kokkotas
We present new results for pulsating stars in general relativity. First we show that the so-called gravitational-wave modes of a neutron star can be excited when a gravitational wa…

Evolving test-fields in a black-hole geometry
Nils Andersson
We consider the initial value problem for a massless scalar field in the Schwarzschild geometry. When constructed using a complex-frequency approach the necessary Green's function…

Spacetime modes of relativistic stars
Nils Andersson, Kostas D. Kokkotas, Bernard F. Schutz
The problem of relativistic stellar pulsations is studied in a somewhat ad hoc approximation that ignores all fluid motions. This {\em Inverse Cowling Approximation} (ICA) is motiv…
