磁星是强磁化的中子星，可以发射静态X射线、重复爆发的软伽马射线，甚至巨大的耀斑。我们研究磁场对孤立磁星结构的影响。恒星结构和磁场配置可以在自洽过程中同时获得。发现磁星质量和半径被强磁场微弱增强。与之前的其他研究不同，磁场无法违反中子星的质量极限。
Magnetars are strong magnetized neutron stars which could emit quiescent X-ray, repeating burst of soft gamma ray, and even the giant flares. We investigate the effects of magnetic fields on the structure of isolated magnetars. The stellar structure together with the magnetic field configuration can be obtained at the same time within a self-consistent procedure. The magnetar mass and radius are found to be weakly enhanced by the strong magnetic fields. Unlike other previous investigations, the magnetic field is unable to violate the mass limit of the neutron stars.
