细胞内粒子（PIC）模拟方法不仅可用于研究地球附近的空间等离子体，还可用于研究宇宙中的天体物理等离子体。在天体物理环境中观察到的高能现象的典型等离子体参数与太阳系中的参数有很大不同，但可以共享许多基本等离子体过程，以便更好地了解等离子体宇宙。这是因为麦克斯韦-弗拉索夫系统在无碰撞等离子体中具有普遍有效性。本章讨论了几项 PIC 模拟研究，主要关注星形等离子体环境中的等离子体加热和粒子加速。
The methodology of particle-in-cell (PIC) simulations is useful for studying not only space plasma in the Earth’s neighborhood but also astrophysical plasmas in the universe. The typical plasma parameters of the high-energy phenomena observed in astrophysical settings are vastly different from those in the solar system, but many fundamental plasma processes can be shared to obtain a better understanding of the plasma universe. This is because of the universal validity of the Maxwell-Vlasov system in collisionless plasmas. This chapter addresses several PIC simulation studies that focus mainly on plasma heating and particle acceleration seen in the astroplasma environment.
