来自GRB 080319 B的裸眼光学闪光：追踪流出物中的衰变中子
Naked-eye optical flash from GRB 080319B: Tracing the decaying neutrons in the outflow
摘要：
对于非定常的重子伽马射线暴（GRB）外流，快质子壳层和慢质子壳层相互碰撞产生高能的软伽玛射线辐射。如果流出物中有大量的中子成分，超相对论中子最初会自由膨胀，直到在更大的半径处衰变。从伽玛射线暴中央发动机喷射出的晚期质子壳层，在为常规的内部冲击提供动力之后，将扫过这些$β-$衰变产物，并产生非常明亮的紫外/光学发射。GRB 080319 B是遥远宇宙中的一次高能爆炸，它产生的肉眼可见的闪光可以用这种方式很好地解释。
英文摘要：
For an unsteady baryonic gamma-ray burst (GRB) outflow, the fast and slow proton shells collide with each other and produce energetic soft gamma-ray emission. If the outflow has a significant neutron component, the ultra-relativistic neutrons initially expand freely until decaying at a larger radius. The late time proton shells ejected from the GRB central engine, after powering the regular internal shocks, will sweep these $β-$decay products and give rise to very bright UV/optical emission. The naked-eye optical flash from GRB 080319B, an energetic explosion in the distant universe, can be well explained in this way.
