宇宙射线的非广延热源?

Nonextensive thermal sources of cosmic rays?

Grzegorz Wilk, Zbigniew Wlodarczyk

摘要:

宇宙射线(CR)的能谱具有幂函数特性,并具有典型的“膝”结构。我们认为,这样的光谱可能产生的一些特定的非统计的温度波动的CR源的“膝盖”结构,反映了这种波动的模式的突然变化。这将导致产生CR的广义非广延统计模型。导致这些影响的可能的物理机制进行了讨论,连同由此产生的化学成分的CR,它遵循实验观察到的丰度的核。

英文摘要:

The energy spectrum of cosmic rays (CR) exhibits power-like behavior with a very characteristic "knee" structure. We consider a possibility that such a spectrum could be generated by some specific nonstatistical temperature fluctuations in the source of CR with the "knee" structure reflecting an abrupt change of the pattern of such fluctuations. This would result in a generalized nonextensive statistical model for the production of CR. The possible physical mechanisms leading to these effects are discussed together with the resulting chemical composition of the CR, which follows the experimentally observed abundance of nuclei.
