最强的宇宙磁体:软Gamma-ray中继器和异常X射线脉冲星

The strongest cosmic magnets: Soft Gamma-ray Repeaters and Anomalous X-ray Pulsars

Sandro Mereghetti

摘要:

两类X射线脉冲星,异常X射线脉冲星和软伽马射线中继星,在过去十年中被认为是最有希望成为磁星的候选者:由磁能驱动的孤立中子星。我回顾这些对象的观测特性,集中在最近的结果,并在磁星模型的解释。替代的解释,特别是那些基于吸积从残留盘,也被认为是。文中还讨论了这些源与其它类型的中子星和天体之间的可能关系。

英文摘要:

Two classes of X-ray pulsars, the Anomalous X-ray Pulsars and the Soft Gamma-ray Repeaters, have been recognized in the last decade as the most promising candidates for being magnetars: isolated neutron stars powered by magnetic energy. I review the observational properties of these objects, focussing on the most recent results, and their interpretation in the magnetar model. Alternative explanations, in particular those based on accretion from residual disks, are also considered. The possible relations between these sources and other classes of neutron stars and astrophysical objects are also discussed.
