Linear adiabatic wave equation and Eddington's homogeneous-sphere pulsation (heliophysics)

Heliophysics application of L0 Runge–Kutta and finite-difference theory. The linear adiabatic wave equation (LAWE) is the coupled 4th-order ODE system governing small spherical-harmonic perturbations (ξ_r, ξ_h, p′, ρ′) of a non-rotating…
