月球作为一个既没有全球性磁场又没有明显大气层的星体，一直以来都认为太阳风是直接作用在月球向阳面且被完全吸收。然而近年来，越来越多的观测与模拟结果表明，太阳风与月表的相互作用由于月表局地磁异常的存在而出现一些”例外”，在一定条件下，可以形成月表微磁层（LMM）。
3D numerical MHD modeling of sunspots with radiation transport
MHD – radiative transfer – Sun sunspots – Sun photosphere – Sun magnetic
2010/11/10
Sunspot fine structure has been modeled in the past by a combination of idealized magneto-convection simulations and simplified models that prescribe the magnetic field and flow structure to a large d...

Context. Oscillations in coronal loops are usually interpreted in terms of uncoupled magnetohydrodynamic (MHD) waves. Examples of these waves are standing transverse motions, interpreted as the kink M...

The possible role of magneto-rotational instability (MRI) and its driven MHD turbulence in
the solar interior is studied on the basis of the linear and nonlinear theories coupling with
physical para...
MHD Simulations of Parker Instability Undergoing Cosmic-Ray Diffusion: Effect of the Initial Equilibrium Conditions on Mixing
cosmic rays magnetohydrodynamics instability numerical simulation
2010/11/9
Parker instability arises from the presence of magnetic fields in a plasma such as the interstellar medium (ISM),wherein the magnetic buoyant pressure expels the gas and causes the gas to move along t...
Cosmological MHD simulations of cluster formation with anisotropic thermal conduction

The paradigm of ideal MHD is investigated in the vicinity of null points of flows and magnetic fields. These null points determine the location and geometrical shape of the heliopause (or other astrop...
