摘要

摘要 根据宇宙射线输运方程,研究了带电高能粒子在日光层磁场中的传播。在粒子角分布低各向异性的近似条件下找到了输运方程的解。日光顶银河宇宙射线的能量分布被用作边界条件。由于太空任务(先锋号、旅行者号、PAMELA、AMS-02 等)的杰出成果,当地星际空间的宇宙射线能谱被认为是已知的。我们计算了不同太阳磁极时期的宇宙射线通量密度。结果表明,在正磁极时期,银河宇宙射线的强度在日赤道附近最大。在行星际磁场具有负极性的时期,宇宙射线的强度随着日曜高度的增加而减小。

Propagation of Galactic Cosmic Rays in the Heliosphere during Minimum Solar Activity Periods

Based on the cosmic ray transport equation, the propagation of charged high-energy particles in heliospheric magnetic fields is considered. The transport equation solution is found in the approximation of low anisotropy in the angular distribution of particles. The energy distribution of galactic cosmic rays at a heliopause is used as a boundary condition. The energy spectrum of cosmic rays in a local interstellar space is considered to be known due to the outstanding results of space missions (Pioneer, Voyager, PAMELA, AMS-02, etc.). The flux density of cosmic rays is calculated in the periods of different solar magnetic polarity. It is shown that the intensity of galactic cosmic rays in positive magnetic polarity periods is maximum near the helioequator. In the periods when the interplanetary magnetic field has a negative polarity, the intensity of cosmic rays decreases with increasing heliolatitude.
