双星系统中的强磁场中子星和磁星

High magnetic field neutron stars and magnetars in binary systems

S. B. Popov

摘要:

双星系统中高磁化中子星的情况还不确定。一方面,所有研究得最好的磁星似乎都是孤立的物体。另一方面,有许多主张基于依赖于模型的X射线双星中中子星的自旋性质或/和光度的分析,支持大场。此外,还有一些结果表明,在密近双星系统中,中子星的活动类似于磁星。大部分理论研究都不支持年龄大于$\sim10^6$ ~ yrs的中子星中磁星尺度场的存在,更不用说活跃衰变了。我提供了一个简短的回顾理论和观测结果与大磁场的中子星在双星的存在,并讨论了未来的研究前景。

英文摘要:

Situation with highly magnetized neutron stars in binary systems is not yet certain. On the one hand, all best studied magnetars seem to be isolated objects. On the other, there are many claims based on model-dependent analysis of spin properties or/and luminosity of neutron stars in X-ray binaries in favour of large fields. In addition, there are a few results suggesting a magnetar-like activity of neutron stars in close binary systems. Most of theoretical considerations do not favour even existence, not speaking about active decay, of magnetar-scale fields in neutron stars older than $\sim10^6$~yrs. However, alternative scenarios of the field evolution exist. I provide a brief review of theoretical and observational results related to the presence of neutron stars with large magnetic field in binaries and discuss perspectives of future studies.
