Modeling solar energetic particle by a relativistic kappa-type distribution

Fuliang Xiao, Qinghua Zhou, Chunxian Li, Aijun Cai2008年Plasma Physics and Controlled FusionIF 2.2出版社

A recently developed relativistic kappa-type (KT) is adopted to model the observed spectra of solar energetic protons. The KT distribution is found to fit well with the observed data in the energies of ∼1–100 MeV and 100–1000 MeV, suggesting that the solar energetic proton flux follows the power law at both the lower energies and the relativistic energies, and the KT distribution may present a further physical insight into those space plasmas where energetic particles exist.

最近開発された相対論的カッパ型分布(KT分布)を用いて、太陽高エネルギー陽子の観測スペクトルをモデル化した。KT分布は、約1〜100 MeVおよび100〜1000 MeVのエネルギー範囲における観測データとよく一致することが見出され、太陽高エネルギー陽子フラックスが低エネルギー域と相対論的エネルギー域の両方でべき乗則に従うことを示唆している。また、KT分布は、高エネルギー粒子が存在する宇宙プラズマに対するさらなる物理的洞察を与える可能性がある。
