Solitary Alfvén Waves
Abstract
Abstract We present the solitary Alfvén wave as an ideal nonlinear Alfvénic solution in the solitary far-field limit and construct a 3D numerical model—an Alfvénon. The model is characterized by an unperturbed far field, quasi-constant ∣ B ∣, and open field-line topology. Direct MHD simulations of the Alfvénon show coherent finite-time propagation, confirming that it behaves as a nonlinear solitary Alfvénic solution under ideal MHD evolution.
