Investigating the Propagation of Alfven Waves in the Solar Corona
Abstract
We present the implementation and first results of the Solar Heliosphere Wind with Alfvén wave Turbulence and extended Magnetohydrodynamics (SHWARMA), a global model from the upper chromosphere to the heliosphere. Through our self-consistent MHD model, we study the response of the corona and solar wind to Alfvén waves (AWs) generated at the photosphere, including the effect on the plasma dynamics as the system reaches a quasi steady-state. The model solves the compressible MHD equations, with low-frequency AWs injected using time-dependent boundary conditions. We investigate the propagation and reflection of the Alfvénic fluctuations in various magnetic field geometries by considering varying super-radially expanding coronal flux tubes. Finally, we discuss our results in the context of recent observations from the Parker Solar Probe.
