Numerical Hydrodynamics of Gamma-Ray Bursts

小行星9416904 该项目的目标是更好地了解产生伽马射线爆发的物理过程。 已经建立了一些模型，在这些模型中，来自相对论性火球的碎片壳层与星际气体碰撞。 分析估计表明，这一模型可能会导致与实际观察到的伽玛射线暴一致。 Katz博士将通过用定量计算取代以前的估计来测试这些模型。 所采用的方法是数值流体力学，它允许在几乎任意复杂的流动中对火球碎片和星际物质的流动进行定量计算。

9416904 Katz The objective of this project is to understand better the physical processes which produce gamma-ray bursts. Models have been developed in which a debris shell from a relativistic fireball collides with interstellar gas. Analytic estimates have shown that this model may lead to gamma-ray bursts consistent with those actually observed. Dr. Katz will test these models by replacing the estimates previously made with quantitative calculations. The method to be employed is that of numerical hydrodynamics, which permits the quantitative calculation of the flow of fireball debris and interstellar matter in almost arbitrarily complicated flows.
