宇宙线加速可能发生在超新星激波膨胀成维持帕克螺旋磁场的星周风时。宇宙射线漂移到两极，产生巨大的宇宙射线压力，这可以产生极密度空腔，宇宙射线通过这些空腔逃逸到激波的上游。这可能与伴随冲击波爆发的伽玛射线暴有关。
Cosmic ray acceleration may occur at a supernova shock expanding into a circumstellar wind sustaining a Parker spiral magnetic field. Cosmic rays drift to the poles producing a large cosmic ray pressure which can generate polar density cavities through which cosmic rays escape upstream of the shock. This may be relevant to gamma-ray bursts accompanying shock breakout.
