摘要

爆发中的软x射线瞬变(SXRTs)显示出与持续的低质量x射线双星(LMXRBs)相似的特性,因此可能包含一个由吸积扭矩旋转的旧弱磁性中子星。现有的x射线观测可以用来约束sxrt中子星的自旋周期和磁场强度。研究了在SRXT静止阶段快速旋转的中子星产生可探测射电脉冲星信号的条件。

Do quiescent soft x‐ray transients contain millisecond radio pulsars?
Soft x‐ray transients (SXRTs) in outburst show properties similar to those of persistent low mass x‐ray binaries (LMXRBs), and therefore likely contain an old weakly magnetic neutron star spun‐up by accretion torques. Available x‐ray observations can be used to constrain the spin period and magnetic field strength of the neutron stars in SXRTs. The conditions under which a detectable radio pulsar signal can be produced by the rapidly rotating neutron star in the quiescent phase of a SRXT are investigated.
