关于缓慢旋转的磁化白矮星

On slowly rotating magnetized white dwarfs

Diana Alvear Terrero, Daryel Manreza Paret, Aurora Perez Martinez

摘要:

在广义相对论的框架内,利用Hartle的形式化理论,研究了旋转磁化的白矮星。磁化的白矮星内部的物质在引入各向异性压力的恒定磁场作用下由粒子状态方程描述。我们的研究是针对低于$10^{13}$ G的磁场值-通过圆柱形度量解决方案获得的最大磁场的阈值-和WD的典型密度。讨论了旋转和磁场的联合作用,计算了相关的量值,如转动惯量、四极矩和偏心率。

英文摘要:

Rotating magnetized white dwarfs are studied within the framework of general relativity using Hartle's formalism. Matter inside magnetized white dwarfs is described by an equation of state of particles under the action of a constant magnetic field which introduces anisotropic pressures. Our study is done for values of magnetic field below $10^{13}$ G -a threshold of the maximum magnetic field obtained by the cylindrical metric solution- and typical densities of WDs. The effects of the rotation and magnetic field combined are discussed, we compute relevant magnitudes such as the moment of inertia, quadrupole moment and eccentricity.
