初始条件对耗散崩溃过程的影响

The Influence of Initial Conditions during Dissipative Collapse

Nolene Ferrari Naidu, Megan Govender

摘要:

从两个不同的初始静态恒星核心(i)弗洛里德斯内部(恒定密度,消失的径向压力)和(ii)怀曼内部(恒定密度,非零的径向压力),我们探讨这两个模型的动力学一旦流体静力学平衡丢失。我们表明,虽然时间的形成的地平线,质量和适当的半径的演变是独立的初始静态配置所选择的,有一个显着的差异,在温度分布的辐射机构的崩溃进行。

英文摘要:

Starting off with two distinct initially static stellar cores (i) Florides interior (constant density, vanishing radial pressure) and (ii) Wyman interior (constant density, nonvanishing radial pressure), we explore the dynamics of these two models once hydrostatic equilibrium is lost. We show that although the time of formation of horizon, evolution of the mass and proper radius are independent of the chosen initially static configurations, there is a significant difference in the temperature profiles of the radiating bodies as the collapse proceeds.
