SGR和AXP是大质量快速旋转的高磁化白矮星:SGR 0418+5729的情况

SGRs and AXPs as massive fast rotating highly magnetized white dwarfs: the case of SGR 0418+5729

Kuantay Boshkayev, Jorge A. Rueda, Remo Ruffini

摘要:

我们描述了一个所谓的低磁场磁星SGR 0418+5729,作为一个大质量的快速旋转的高磁化白矮星以下Malheiro等。等人,2012年。我们给出了这些源的质量,半径,转动惯量和磁场的界限,通过要求现实的广义相对论均匀旋转配置的稳定性。基于这些参数,我们改进了SGR 0418+5729自旋下降速率下限的理论预测。此外,我们还计算了与预测的表面磁场相对应的电子回旋频率。

英文摘要:

We describe one of the so-called low magnetic field magnetars SGR 0418+5729, as a massive fast rotating highly magnetized white dwarf following Malheiro et. al. 2012. We give bounds for the mass, radius, moment of inertia, and magnetic field for these sources, by requesting the stability of realistic general relativistic uniformly rotating configurations. Based on these parameters, we improve the theoretical prediction of the lower limit of the spin-down rate of SGR 0418+5729. In addition, we compute the electron cyclotron frequencies corresponding to the predicted surface magnetic fields.
