摘要
基于Huang,Y.F.等人的统一动力学模型,研究了星际介质环境下各向同性火球所抛壳层的动力学量随时间的演化,考虑了同步自吸收效应,用数值计算方法得到不同频率下随时间演化的伽玛暴余辉,同柱状喷流下伽玛暴余辉比较,得出相应结论.
Based on the generic dynamical model proposed by Huang et al.,the evolution of dynamics with time in the interstellar medium is studied in detail by numerical methods. Taking the effect of synchrotron self-absorption into account,the evolution under different frequencies of afterglow with time is obtained with numerical calculation methods. The paper draws the corresponding conclusions by comparing the data with the cylindrical jet model.
