反向旋转粒子圆柱壳的相对论动力学

Relativistic dynamics of cylindrical shells of counter-rotating particles

V. H. Hamity, M. A. Cecere, D. E. Barraco

摘要:

虽然无限长圆柱体不是天体物理学的实体,但我们可以从它的基本性质中了解到很多关于引力波产生的特征,以及在半径很小的范围内,物质在这种壳层中的行为。我们描述的分析模型,使用动力学理论的物质和结的条件,通过壳,以获得其运动方程。静态解决方案的性质进行了分析,无论是一个单一的壳,以及为两个同心壳。在第二种情况下,对于时间相关的外壳,我们积分数值的运动方程的系统的常数的几个值。此外,在科马尔质量方面的简要描述给出了占系统发射的引力波能量。

英文摘要:

Although infinite cylinders are not astrophysical entities, it is possible to learn a great deal about the basic qualitative features of generation of gravitational waves and the behavior of the matter conforming such shells in the limits of very small radius. We describe the analytical model using kinetic theory for the matter and the junction conditions through the shell to obtain its equation of motion. The nature of the static solutions are analyzed, both for a single shell as well as for two concentric shells. In this second case, for a time dependent external shell, we integrate numerically the equation of motion for several values of the constants of the system. Also, a brief description in terms of the Komar mass is given to account for the gravitational wave energy emitted by the system.
