论文摘要
对于扩展的球形相对论冲击,我们得出了下游发射区的参数与遥远观察者测量的数量之间的关系。这些关系是根据无量纲的有效系数结合了自动尺寸估计的。我们的计算考虑了冲击的洛伦兹因子的演变,由于冲击的前曲率而引起的几何延迟以及洛伦兹提高频率和亮度的角度依赖性。该关系主要用于在伽马射线爆发余辉研究中应用,尽管它们可能具有更广泛的用途。
For an expanding spherical relativistic shock, we derive relations between the parameters of downstream emitting zone and the quantities measured by a distant observer. These relations are formulated in terms of dimensionless effective coefficients combined with self-evident dimensional estimates. Our calculations take into account evolution of the shock's Lorentz factor, geometrical delay due to the shock's front curvature, and angular dependence of Lorentz boost for frequency and brightness. The relations are designed primarily for application in Gamma-Ray Burst afterglow studies, although they may have a broader use.
