Description
The accurate modelling of neutron star oscillations is essential as we prepare for the next generation of gravitational-wave detectors, which will be able to probe the rich astrophysical content of post-merger signals. In this talk, I will present recent updates to ROXAS, a spectral code to numerically simulate the dynamical evolution of perturbed rotating neutron stars. ROXAS uses a well-balanced formulation of the hydrodynamical equations within the conformal flatness approximation, and extracts the emitted gravitational waves. Current work focuses on extending the code to support differentially rotating stars, a key step towards a more realistic modelling of post-merger remnants.
