Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]
, 2014 Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Simulations of Incompressible Magnetohydrodynamic Turbulence [PDF]
The Astrophysical Journal, 2001 We simulate incompressible MHD turbulence using a pseudospectral code. Our major conclusions are: (1) MHD turbulence is most conveniently described in terms of counterpropagating shear Alfven and slow waves. Shear Alfven waves control the cascade dynamics. Slow waves play a passive role and adopt the spectrum set by the shear Alfven waves.

Stream-aligned Magnetohydrodynamics for Solar Wind Simulations [PDF]
The Astrophysical Journal, 2021 Abstract We present a reduced magnetohydrodynamic (MHD) mathematical model describing the dynamical behavior of highly conducting plasmas with frozen-in magnetic fields, constrained by the assumption that there exists a frame of reference, where the magnetic field vector,

The Formation of Star-forming Disks in the TNG50 Simulation
The Astrophysical Journal, 2023 We investigate the disk formation process in the TNG50 simulation, examining the profiles of SFR surface density (Σ _SFR ), gas inflow and outflow, and the evolution of the angular momentum of inflowing gas particles.

Global simulations of galactic dynamo driven by cosmic-rays and exploding magnetized stars [PDF]
, 2008 We conduct global galactic--scale magnetohydrodynamical (MHD) simulations of the cosmic--ray driven dynamo. We assume that exploding stars deposit small--scale, randomly oriented, dipolar magnetic fields into the differentially rotating ISM, together ...

The Astrophysical Journal Supplement Series, 2023 A new magnetohydrodynamics (MHD) simulation model of the global solar corona and solar wind is presented. The model covers the range of heliocentric distance from 2.5 solar radii, so that coronal mass ejections at the earliest phase near the Sun can be ...

Eclipsing Time Variations from 3D Magnetohydrodynamical Simulations
, 2023 Magnetic fields are ubiquitous in the Universe. In particular, the magnetic activity of the Sun has been observed for centuries and studied for more than a century. Nowadays we know that most stars are magnetized.

The Astrophysical Journal, 2023 In this paper, we present a new tool to investigate the interaction of the solar wind with Venus with the approach of a global multifluid magnetohydrodynamics (MHD) model. The continuity, momentum, and energy equations for H ^+ , O ^+ , ${{\rm{O}}}_{2}^{+

Avalanches in magnetohydrodynamical simulations
Physical Review EScale invariance is a hallmark of many natural systems, including solar flares, where energy release spans a vast range of scales. Recent computational advances, at the level of both algorithmics and hardware, have enabled high-resolution magnetohydrodynamical (MHD) simulations to span multiple scales, offering new insights into magnetic energy ...
