论文摘要

我们通过使用Eclipse时正时技术提出了LMXB XTE J1710-281的轨道周期演变的更新测量。使用XMM-Newton,Suzaku,Rxte,Chandra和Astrosat观测值获得的数据,我们报告了21种X射线中期时期的新测量结果。我们在XTE J1710-281中发现了第三个轨道周期故障,F检验的错误警报概率约为0.7%,即出现第三个故障,并报告该系统中轨道时期的四个不同时期的检测。这项工作对第二轨道周期故障的发生更加可靠地估计。然而,第三个故障的发生时期在MJD 55726至56402之间的限制很差。我们将连续时期之间轨道时期的突然变化放在1.48 ms,0.97 ms和0.45 ms的下限。我们讨论了我们的发现在伴侣恒星的磁性和可能的​​散射事件中的含义,并在该二进制系统周围具有围绕二进制对象。

We present an updated measurement of orbital period evolution of LMXB XTE J1710-281 by using eclipse timing technique. Using data obtained with XMM-Newton, Suzaku, RXTE, Chandra and AstroSat observatories, we report 21 new measurements of X-ray mid-eclipse times. We have discovered a third orbital period glitch in XTE J1710-281 with an F-test false alarm probability of ~0.7% for occurrence of the third glitch and report detection of four distinct epochs of orbital period in this system. This work presents a more robust estimation of occurrence of the second orbital period glitch. However, the epoch of occurrence of the third glitch is poorly constrained, between MJD 55726 to 56402. We have put lower limits of 1.48 ms, 0.97 ms and 0.45 ms, on sudden changes in orbital period between the successive epochs. We discuss the implications of our findings in context of magnetic nature of the companion star and possible scattering events with circum-binary objects around this binary system.
