9311888 Petrosian The primary goal of this project is to understand the energy release and particle acceleration mechanisms in solar flares. It is believed that the source of energy of flares is the current carrying magnetic field and that the bulk of this energy goes into the acceleration of particles. Most direct information on these processes comes from microwave, hard X-ray and gamma-ray observations of the impulsive phase of flares, and it is through comparison of these observations with theoretical results that insight can be gained into this important problem. In the theoretical aspect of this project the goal is to improve the treatment of the acceleration process and unify it with the transport and radiative aspects. The model results will be compared with spectral data from solar flares obtained by several spacecraft. The results from this project will not only be important in the understanding of the flare problem, but will be useful in other areas of high energy astrophysics, such as magnetospheric phenomena around planets and compact stars and in the nuclei of active galaxies. ***

小行星9311888 该项目的主要目标是了解太阳耀斑中的能量释放和粒子加速机制。 据信，耀斑的能量来源是载流磁场，大部分能量用于粒子的加速。 关于这些过程的最直接的信息来自于对耀斑脉冲相的微波、硬X射线和伽马射线观测，正是通过将这些观测结果与理论结果进行比较，才能深入了解这一重要问题。 在这个项目的理论方面，目标是改善加速过程的处理，并统一它与运输和辐射方面。 模型结果将与几个航天器获得的太阳耀斑光谱数据进行比较。 该项目的结果不仅对理解耀斑问题很重要，而且对高能天体物理学的其他领域也很有用，如行星和致密恒星周围的磁层现象以及活动星系核中的磁层现象。 ***
