广义相对论坡印廷-罗伯逊效应的新研究

New approaches to the general relativistic Poynting-Robertson effect

Vittorio De Falco

摘要:

目的:通过引入不同的补充方法,对广义相对论Poynting-Robertson效应进行了系统的研究,主要分为两类:(1)在理论评估和模型的简单方面进行改进;(2)从这类系统中提取数学和物理信息,以便将方法或结果推广到其他类似结构的物理系统。方法/分析:我们使用这些理论方法:观测器分裂形式的相对性;拉格朗日形式和瑞利势与一种新的积分方法;李雅普诺夫稳定性理论。研究结果:我们确定了广义相对论坡印廷-罗伯逊效应模型的三维配方。我们确定的瑞利势的解析形式,并讨论其影响。我们证明了临界超曲面(引力和辐射力之间存在平衡的区域)是稳定的配置。新颖性/改进:我们的新贡献是:介绍了三维描述;在广义相对论文献中首次确定了广义相对论瑞利势;提供了一个替代的、一般的和更优雅的临界超曲面稳定性的证明。

英文摘要:

Objectives: A systematic study on the general relativistic Poynting-Robertson effect has been developed so far by introducing different complementary approaches, which can be mainly divided in two kinds: (1) improving the theoretical assessments and model in its simple aspects, and (2) extracting mathematical and physical information from such system with the aim to extend methods or results to other similar physical systems of analogue structure. Methods/Analysis: We use these theoretical approaches: relativity of observer splitting formalism; Lagrangian formalism and Rayleigh potential with a new integration method; Lyapunov theory os stability. Findings: We determined the three-dimensional formulation of the general relativistic Poynting-Robertson effect model. We determine the analytical form of the Rayleigh potential and discuss its implications. We prove that the critical hypersurfaces (regions where there is a balance between gravitational and radiation forces) are stable configurations. Novelty /Improvement: Our new contributions are: to have introduced the three-dimensional description; to have determined the general relativistic Rayleigh potential for the first time in the General Relativity literature; to have provided an alternative, general and more elegant proof of the stability of the critical hypersurfaces.
