Description
The oscillation modes of neutron stars encode valuable information about their internal structure and dense-matter equation of state. These signatures can be studied through gravitational waves, with next-generation detectors offering new opportunities thanks to their improved sensitivity, which will provide better access to the post-merger phase of binary neutron stars.
In this talk, I will present recent developments for ROXAS, a spectral code designed to simulate the dynamical evolution of perturbed rotating neutron stars using a formalism based on primitive variables, allowing the extraction of oscillation frequencies from the resulting dynamics. In particular, I will discuss recent results obtained for differentially rotating configurations and present ongoing efforts to incorporate thermal effects.
