Time-dependent coronal shock acceleration of energetic solar flare particles

摘要: A global time-dependent model is presented for the coronal and interplanetary shock acceleration propagation of energetic solar flare particles. The calculations are carried out to help prove that particles responsible event data gathered in space. based on theory diffusive acceleration, requires particle speeds be much greater than bulk velocities. Also, sufficient scattering must occur upstream downstream mean free path smaller characteristic scale lengths, which causes same encounter repeatedly. spherically symmetric wave assumed, leads emission configuration impulsively monoenergetically emitted Consideration given by compression at front, adiabatic deceleration divergent flow, temporal evolution three-dimensional geometry corona. used generate normalized proton omnidirectional distributions 1 AU front. spectral exhibit trends similar those observational data, especially times distribution profiles AU. 92 references
