论文摘要
我们已经提出了第一个关节{\ it xmm-newton}和{\ it nustar}分析毫秒Pulsar（MSP）二进制PSR J1653 $ - $ 0158。从光学和伽马射线观测中推断出的75分钟轨道周期以及伽马射线中的1.97 ms脉动表明，该系统是已知已知的最紧凑的黑寡妇MSP系统。在{\ it xmm-newton}和{\ it nustar}数据中未检测到轨道周期，这可能是由于观测值中获得的光子计数不足所致。将PSR J1653 $ - $ 0158的关节X射线频谱与功率定律相吻合提供了光子指数$γ= 1.71 \ pm 0.09 $。 （$ 0.2-40 $）〜keV频段中源的X射线光度为$ 1.18 \ times 10^{31}} \; \！{\ rm erg〜s}^{ - 1} $，用于0.84〜kpc的距离。我们已经表明，可以通过在二元内休克中加速的电子的同步辐射来解释宽波段X射线频谱，并且在{\ it fermi}数据中检测到的伽马射线是来自脉冲磁带中电子和正面的曲率辐射。我们对Tidarren系统PSR〜J1653--0158和PSR〜J1311--3430的运动学分析表明，两个Tidarren系统可能起源于银河系磁盘。
We have presented the first joint {\it XMM-Newton} and {\it NuSTAR} analysis of the millisecond pulsar (MSP) binary PSR J1653$-$0158. The 75-minute orbital period inferred from optical and gamma-ray observations together with the 1.97-ms pulsation in the gamma-rays indicate that this system is the most compact Black Widow MSP system known to date. The orbital period was not detected in the {\it XMM-Newton} and {\it NuSTAR} data, probably due to insufficient photon counts obtained in the observations. Fitting the joint X-ray spectrum of PSR J1653$-$0158 with a power law gives a photon index $Γ= 1.71 \pm 0.09$. The X-ray luminosity of the source in the ($0.2-40$)~keV band is deduced to be $1.18 \times 10^{31}\;\!{\rm erg~s}^{-1}$, for an adopted distance of 0.84~kpc. We have shown that the broad-band X-ray spectrum can be explained by synchrotron radiation from electrons accelerated in the intra-binary shock, and the gamma-rays detected in the {\it Fermi} data are curvature radiations from electrons and positrons in the pulsar magnetosphere. Our kinematic analysis of the Tidarren systems PSR~J1653--0158 and PSR~J1311--3430 indicates that the two Tidarren systems are likely to have originated in the Galactic Disk.
