DOI: 10.1029/2020ja028187
Abstract: We investigate how initially high-m, poloidal Alfvén waves evolve using a numerical model solving the ideal, cold, linear magnetohydrodynamic (MHD) equations in a 2-D dipole coordinate system. The curved magnetic geometry provides a key difference… read more here.

DOI: 10.1088/1361-6587/ab5b32
Abstract: This paper is concerned with the structure of the ion-ion hybrid (IIH) waves in the multicomponent magnetospheric plasma in the dipole geomagnetic field model. Like the Alfv\'en waves, in the IIH waves the field line… read more here.

DOI: 10.1088/1741-4326/aac33f
Abstract: Alfven Eigenmodes are destabilized at the DIII-D pedestal during transient beta drops in high poloidal beta discharges with internal transport barriers (ITBs), driven by n=1 external kink modes, leading to energetic particle losses. There are… read more here.
