考虑再加速的cosmic ray传播模型的功率要求及对二阶费米加速理论的评述

Power requirements for cosmic ray propagation models involving re-acceleration and a comment on second order Fermi acceleration theory

Andrew Thornbury, Luke O'C. Drury

摘要:

在考虑再加速的传播模型中,我们导出了星际湍流向银河系宇宙射线传递能量的解析表达式。这是用来估计在这种模式所需的功率和相对重要性的主要加速对再加速。分析提供了一个正式的数学证明费米的启发式帐户的二阶加速在他的经典1949年的文件。

英文摘要:

We derive an analytic expression for the power transferred from interstellar turbulence to the Galactic cosmic rays in propagation models which include re-acceleration. This is used to estimate the power required in such models and the relative importance of the primary acceleration as against re-acceleration. The analysis provides a formal mathematical justification for Fermi's heuristic account of second order acceleration in his classic 1949 paper.
