摘要

摘要在宇宙学基本问题（与太阳原行星盘存在初期的重建有关）的框架内，提出了一个平均流尺度上的 MHD 闭合方程系统。该系统用于对吸积原行星盘及其日冕的结构和演变进行相互一致的模拟问题的数值求解。考虑的是一个薄（但光学厚度大）盘的模型，其中考虑到了运动粘度和磁粘度引起的湍流耗散、介质的不透明性、来自周围空间的吸积、湍流αω动力对磁场产生的作用，以及盘和其日冕之间的磁力和能量相互作用。

On the Modeling of a Compressible MHD Turbulence of an Accretion Protoplanetary Disk

Abstract

In the framework of the basic problem of cosmogony, which is associated with the reconstruction of the protoplanetary solar disk at the very early stages of its existence, a closed system of MHD equations on the mean flow scale is formulated. This system is intended for numerical solution of problems on interconsistent simulation of the structure and evolution of the accretion protoplanetary disk and its corona. The model of a thin (but optically thick) disk is considered, in which turbulence dissipation due to kinematic and magnetic viscosity, opaqueness of the medium, accretion from the surrounding space, and the action of turbulent αω dynamo on the generation of magnetic field, as well as the magnetic force and energy interaction between the disk and its corona are taken into account.

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
