静态时空多极矩的源积分

Source integrals of multipole moments for static space-times

J. L. Hernandez-Pastora, J. Martin, E. Ruiz

摘要:

以相对论源质量的Komar定义为出发点,引入相对论多极矩的体积积分。经典的高斯定理的某种推广被用来重写这些多极矩作为积分在一个表面上的无穷远。因此,它表明,上述推广导致渐近相对论多极矩(ARMM),恢复Geroch或索恩的多极,当积分在渐近Carnival调和坐标进行评估。索恩定义和经典理论的时刻的关系。

英文摘要:

The definition of Komar for the mass of a relativistic source is used as a starting point to introduce volume integrals for Relativistic Multipole Moments (RMM). A certain generalization of the classical Gauss theorem is used to rewrite these multipole moments as integrals over a surface at the infinity. Therefore it is shown that the above generalization leads to Asymptotic Relativistic Multipole Moments (ARMM), recovering the multipoles of Geroch or Thorne, when the integrals are evaluated in asympotically cartesian harmonic coordinates. Relationships regarding the Thorne definition and the classical theory of moments are shown.
