Teukolsky主方程的一类精确解

Classes of Exact Solutions to the Teukolsky Master Equation

Plamen P. Fiziev

摘要:

Teukolsky主方程是研究线性近似下Kerr度规扰动的基本工具。它允许分离变量,从而产生Teukolsky径向方程和Teukolsky角方程。我们在这里提出了一个统一的描述的所有类的精确解,这些方程的合流Heun函数。大类新的精确解的发现和分类方面的特征属性。特别注意的是多项式的解决方案,这是奇异的,并引入准直单向运行波。结果表明,适当的线性组合,这样的解决方案可以提出有界的单向运行波。这种类型的波可能适合作为观测到的天体物理喷流的模型。

英文摘要:

The Teukolsky Master Equation is the basic tool for study of perturbations of the Kerr metric in linear approximation. It admits separation of variables, thus yielding the Teukolsky Radial Equation and the Teukolsky Angular Equation. We present here a unified description of all classes of exact solutions to these equations in terms of the confluent Heun functions. Large classes of new exact solutions are found and classified with respect to their characteristic properties. Special attention is paid to the polynomial solutions which are singular ones and introduce collimated one-way-running waves. It is shown that a proper linear combination of such solutions can present bounded one-way-running waves. This type of waves may be suitable as models of the observed astrophysical jets.
