标题： RXTE Observations of PSR J1105-6107

摘要： 我们报告使用Rossi X-ray Timing Explorer获得的年轻、高能射电脉冲星PSR J1105-6107的X射线观测结果。 我们对比例计数器阵列数据的定时分析未发现该天体的X射线脉动证据。 我们在2-10 keV波段设定了脉冲X射线通量的新上限，占空比为0.5，上限为18%。 我们改进的上限支持这样的假设，即ASCA X射线卫星在PSR J1105-6107方向上观测到的X射线辐射是脉冲星驱动的同步加速星云的结果。 显示英文摘要

摘要： We report on X-ray observations of the young, energetic radio pulsar PSR J1105-6107 obtained using the Rossi X-ray Timing Explorer. Our timing analysis of Proportional Counter Array data finds no evidence for X-ray pulsations from this source. We set a new upper limit on the pulsed X-ray flux from the pulsar of 18% in the 2-10 keV band, for a duty cycle of 0.5. Our improved upper limit supports the hypothesis that the X-ray emission seen by the ASCA X-ray satellite in the direction of PSR J1105-6107 is the result of a pulsar-powered synchrotron nebula.
