论文摘要

薄层近似中能量保护的理论已扩展到特殊的相对论。分析了四个模型的间隔介质密度,这些模型由恒定,幂定律,指数和emden(n = 5)的密度表示。天体物理结果以数值方式呈现,除了泰勒在原点周围的四个轨迹的扩展外。模型的自由参数专门针对SN1993J,为此,半径与时间是已知的。提出了一些关于时间扩张的评估。

The theory of the conservation of energy in the thin layer approximation has been extended to special relativity. Four models for the density of the circumstellar medium are analyzed, which are represented by constant, power law, exponential and Emden (n=5) profile for density. The astrophysical results are presented in a numerical way, except for a Taylor expansion of the four trajectories in the surrounding of the origin. The free parameters of the models are particularized for SN1993j, for which the radius versus time is known. Some evaluations on the time dilation are presented.
