论文摘要
本文研究了一个相对论的积聚厚的盘模型，该模型由变形的紧凑型物体提出，该对象通过使用$ \ rm q $ - metric，从球形到四极力矩略有偏差。该度量是爱因斯坦方程中最简单的渐近平坦解，具有四极矩。这项工作旨在通过研究这些时空中这些平衡序列的这些平衡序列的性能，研究四极力矩与厚磁盘模型的参数的影响。我们采用了不同的角动量分布，并根据文献中先前考虑的方法的组合讨论了构建这种环形盘模型的程序。我们已经显示了此相对论积聚盘模型的属性及其对初始参数的依赖性。此外，该理论模型可以用作数值模拟的初始数据。
This paper studied the relativistic accretion thick disc model raised by a deformed compact object that slightly deviated from spherical up to the quadrupole moment by utilising $\rm q$-metric. This metric is the simplest asymptotically flat solution of Einstein's equation with quadrupole moment. This work aims to study the effects of quadrupole moments in combination with the parameters of the thick magnetised disc model via studying the properties of these equilibrium sequences of magnetised, non-self-gravitating discs in this space-time. We employed different angular momentum distributions and discussed the procedure of building this toroidal disc model based on a combination of approaches previously considered in the literature. We have shown the properties of this relativistic accretion disc model and its dependence on the initial parameters. Besides, this theoretical model can be served as the initial data for numerical simulations.
