Abstract

An analytical semiempirical model of the bow shock based on theoretical MGD calculations, accurate analytical solutions, and experimental data continues to be developed. The model parameters have a clear physical meaning. For cases in which the magnetic field of the solar wind is directed along its velocity or is perpendicular to the velocity vector, analytical expressions that allow calculating the parameters of the bow shock—the distance to the subsolar point, the radius of the curvature, and the bluntness at the subsolar point—are obtained via renormalization of the previously developed detailed gas-dynamic model. For the case in which the magnetic field vector is perpendicular to the solar wind velocity vector, it is shown that it is sufficient for an analytical description of the bow shock surface to approximate its parameters in two perpendicular planes.

摘要

继续开发基于理论MGD计算，准确的解析解和实验数据的弓形冲击的分析半经验模型。模型参数具有明确的物理含义。对于太阳风的磁场沿其速度方向或垂直于速度矢量的情况，可以使用解析表达式来计算船首冲击的参数，即到太阳下点的距离，曲率半径和通过重新规范先前开发的详细气体动力学模型，可以得到在太阳下点的钝度。对于磁场矢量垂直于太阳风速矢量的情况，
