论文摘要
高磁场(高-B)脉冲星是桥接磁铁和常规旋转动力脉冲星的关键来源,从而了解磁性活性的起源。我们估计最年轻的高脉冲脉冲PSR PSR J1208-6238的X射线通量上的上限很紧。 Chandra 10 KS观察没有显示出明显的来源。根据发射模型,内在的0.5-7 keV通量上的3sigma上限至(2.2-10.0)E-14 ERG/s/cm2。
High magnetic field (high-B) pulsars are key sources to bridge magnetars and conventional rotation powered pulsars, and thus to understand the origin of magnetar activities. We have estimated a tight upper-limit on the X-ray flux of one of the youngest high-B pulsars PSR J1208-6238 for the first time; a Chandra 10 ks observation shows no significant source. Depending on the emission models, the 3sigma upper-limit on the intrinsic 0.5-7 keV flux to (2.2-10.0)e-14 erg/s/cm2.
