来自热源的宇宙射线

Cosmic rays from thermal sources

Z. Wlodarczyk, G. Wilk

摘要:

宇宙射线(CR)的能谱具有幂函数特性,并具有非常典型的“膝”结构。我们考虑一个广义的统计模型的生产过程中的宇宙射线占这样的行为在一个自然的方式,无论是通过假设存在的温度波动的CR源,或通过假设特定的温度分布的CR源。这两种可能性都产生了所谓的Tsallis统计量,并导致了幂型分布。我们认为,“膝”结构出现的结果突然变化的波动源的CR。它的可能起源进行了简要讨论。

英文摘要:

Energy spectrum of cosmic rays (CR) exhibits power-like behavior with very characteristic "knee" structure. We consider a generalized statistical model for the production process of cosmic rays which accounts for such behavior in a natural way either by assuming existence of temperature fluctuations in the source of CR, or by assuming specific temperature distribution of CR sources. Both possibilities yield the so called Tsallis statistics and lead to the power-like distribution. We argue that the "knee" structure arises as result of abrupt change of fluctuations in the source of CR. Its possible origin is briefly discussed.
