TL;DR
This paper investigates how slow rotation affects crustal oscillations in relativistic stars, comparing results with Newtonian models across various neutron star configurations.
Contribution
It provides the first detailed analysis of rotational effects on crustal modes in relativistic stars with different equations of state.
Findings
Rotation influences torsional and spheroidal crustal modes
Relativistic effects modify oscillation frequencies compared to Newtonian models
Results vary across different neutron star models and equations of state
Abstract
We study low-amplitude crustal oscillations of slowly rotating relativistic stars consisting of a central fluid core and an outer thin solid crust. We estimate the effect of rotation on the torsional toroidal modes and on the interfacial and shear spheroidal modes. The results compared against the Newtonian ones for wide range of neutron star models and equations of state.
