磁星1E 2259+586中观测到的抗毛刺的简单机制

A simple mechanism for the anti-glitch observed in magnetar 1E 2259+586

Federico García, Ignacio F. Ranea-Sandoval

摘要:

在这篇简短的文章中,我们提出了一个简单的内部机制,解释了最近在磁星1E 2259+586中观察到的抗毛刺现象。我们认为内部环形磁场分量的衰减会使原本稳定的长扁星结构失稳。随后,恒星结构的重新排列将产生一个“更球形”的结构,导致整个恒星突然向下自旋。我们在这里提出了一些数量级的计算,给信心,这种情况下,使用最简单的分析恒星模型,并让更详细的计算更技术性的未来文件。

英文摘要:

In this short communication we present a simple internal mechanism that accounts for the recently observed anti-glitch in magnetar 1E 2259+586. We propose that the decay of an internal toroidal magnetic field component would de-stabilize an originally stable prolate star configuration. Then, the subsequent rearrangement of the stellar structure would give rise to a "more spherical" configuration, resulting in a sudden spin-down of the whole star. We present here some order of magnitude calculation to give confidence to this scenario, using the simplest analytical stellar model and let more detailed calculations for a more technical future paper.
