SummarySeismic vibrations on Earth contain information about the structure of our planet, seismic vibrations on distant stellar remnants could shed light not only on the star itself but also on the basic constituents of all matter. The objects under study: neutron stars with strong magnetic fields. The method: a new model that combines both the elastic shear vibrations of the crust and pulsations caused by the magnetic field. Current X-ray observations can only be explained by the coupled vibrations and the model even predicts how high-energy radiation is modulated by these oscillations.
