Journal of Scientific Computing: A Non-perturbative Approach to Computing Seismic Normal Modes in Rotating Planets
A continuous Galerkin method based approach is presented to compute the seismic normal modes of rotating planets. Special care is taken to separate out the essential spectrum in the presence of a fluid outer core using a polynomial filtering eigensolver. The relevant elastic-gravitational system of equations, including the Coriolis force, is subjected to a mixed […]
