Abstract

Based on the theory of diffusive shock acceleration of charged particles, we have numerically studied the spectra of protons produced by a fast shock with a speed of 5000 km s^–1 in the lower solar corona with known solar plasma parameters. We show that protons with energies \( \gtrsim \)10⁵ MeV can be produced at a distance up to 3\({{R}_{ \odot }}\) (\({{R}_{ \odot }}\) is the solar radius) within 274 s.

较低太阳日冕中快速撞击前的太阳宇宙射线加速

摘要

基于带电粒子的扩散冲击加速度理论，我们对已知太阳等离子体参数的下太阳日冕中以5000 km s ^–1的速度以5000 km s ^–1的速度快速冲击产生的质子的光谱进行了数值研究。我们表明，能量为\（\ gtrsim \） 10 ⁵ MeV的质子可以产生的距离最大为3 \（{{R} _ {\ odot}} \）（\（{{R} _ {\ odot} } \）是274 s之内的太阳半径）。
