Multidimensional Simulations of Core Convection
The cores of main sequence intermediate- and high-mass stars are convective. Mixing at the radiative–convective boundary, waves excited by the convection, and magnetic fields generated by convective dynamos all influence the main sequence and post-main ...

Trefftz spectral method for elliptic equations of general type
A new numerical method for 2D linear elliptic partial differential equations in an arbitrary geometry is presented. The special feature of the method presented is that the trial functions, which are used to approximate a solution, satisfy the PDE only ...

Transition to Equilibrium and Coherent Structure in Ideal MHD Turbulence, Part 2
We continue our study of the transition of ideal, homogeneous, incompressible, magnetohydrodynamic (MHD) turbulence from non-equilibrium initial conditions to equilibrium using long-time numerical simulations on a 1283 periodic grid.

First Principles Description of Plasma Expansion Using the Expanding Box Model
Multi-scale modeling of expanding plasmas is crucial for understanding the dynamics and evolution of various astrophysical plasma systems such as the solar and stellar winds. In this context, the Expanding Box Model (EBM) provides a valuable framework to

Anisotropic three-dimensional MHD turbulence [PDF]
Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic field.

Lax representations for the magnetohydrodynamics equations [PDF]
We find Lax representations and derive special B{\"a}cklund transformations for the reduced magnetohydrodynamics equations and the ideal magnetohydrodynamics ...

One-form superfluids & magnetohydrodynamics
We use the framework of generalised global symmetries to study various hydrodynamic regimes of hot electromagnetism. We formulate the hydrodynamic theories with an unbroken or a spontaneously broken U(1) one-form symmetry. The latter of these describes a

Relativistic magnetohydrodynamics
We present the equations of relativistic hydrodynamics coupled to dynamical electromagnetic fields, including the effects of polarization, electric fields, and the derivative expansion.
