复杂结构恒星系统中引力波形式的开普勒参数计算方法

Computational Approach to Gravitational Waves Forms in Stellar Systems as Complex Structures through Keplerian Parameters

Ivana Bochicchio, Mariafelicia De Laurentis, Ettore Laserra

摘要:

本文在四极近似下研究了恒星动力学结构作为复杂系统的引力波发射。在推导了引力波的光度、总能量输出和引力辐射振幅的解析表达式后,我们提出了一种计算方法来计算作为开普勒参数函数的椭圆、圆、抛物和双曲线轨道上的引力波形式。

英文摘要:

In this paper we investigate the gravitational waves emission by stellar dynamical structures as complex systems in the quadrupole approximation considering bounded and unbounded orbits. Precisely, after deriving analytical expressions for the gravitational wave luminosity, the total energy output and gravitational radiation amplitude, we present a computational approach to evaluate the gravitational wave-forms from elliptical, circular, parabolic and hyperbolic orbits as a function of Keplerian parameters.
