TL;DR: Taimourzadeh et al. as discussed by the authors verified and validated linear simulations of Alfvén eigenmodes in the current ramp phase of DIII-D L-mode discharge #159243 using gyrokinetic, MHD hybrid, and eigenvalue codes.
Journal ArticleDOI
Characterizing the feedback of magnetic field on the differential rotation of solar-like stars
TL;DR: In this article, the authors used the ASH code to model the convective dynamo of solar-like stars at various rotation rates and masses, hence different effective Rossby numbers.

TL;DR: In this paper, the authors used the reduced MHD equations in a full 3D system coupled with equations of density and parallel velocity moments for the energetic particles as well as the geodesic acoustic wave dynamics, to study the properties of the instabilities observed in the DIII-D high poloidal beta discharges and identify the conditions to trigger the bifurcation.
