Dynamics of Bursty Waves in Space and Astrophysics

空间和天体物理学中爆发波的动力学。空间等离子体中的波通常发生在具有广泛变化的场的爆发中，并且伴随着它们的驱动粒子分布持续存在，持续时间出乎意料地长。这些特征不能用标准等离子体理论来解释，而可以用随机生长理论（SGT）来解释。最近的观测表明，SGT在太空中广泛适用。我们建议通过研究一般SGT和已知SGT系统中SGT的动力学演变，使SGT完全定量化，并针对空间和天体物理中长期无法解释的重大射电现象，建立基于SGT和相关波/辐射过程的观测测试理论。\ r \ n

Dynamics of Bursty Waves in Space and Astrophysics. Waves in space plasmas typically occur in bursts with widely variable fields and persist, with their driving particle distributions, for unexpectedly long times. These features cannot be accounted for with standard plasma theory but are explained naturally by stochastic growth theory (SGT). Recent observations show SGT to be widely applicable in space. We propose to make SGT fully quantitative, by studying the dynamical evolution to SGT in general and in known SGT systems, and to develop and observationally test theories based on SGT and associated wave/radiation processes for major, long-unexplained radio phenomena in space and in astrophysics. \r\n
