Nonlinear Damping and Field-aligned Flows of Propagating Shear Alfv\'en Waves with Braginskii Viscosity

Understand

Braginskii MHD provides a more accurate description of many plasma environments than classical MHD since it actively treats the stress tensor using a closure derived from physical principles.

• Stress tensor effects nonetheless remain relatively unexplored for solar MHD phenomena, especially in nonlinear regimes.
• This paper analytically examines nonlinear damping and longitudinal flows of propagating shear Alfv\'en waves.
• Most previous studies of MHD waves in Braginskii MHD considered the strict linear limit of vanishing wave perturbations.
