论文摘要
X射线通量和脉冲周期波动中的脉冲脉冲发生器传达了有关磁盘 - 磁层相互作用的重要信息。结果表明，可以根据标准的磁中心液体积分扭矩来分析同时通量和周期测量值，以产生三个隐藏状态变量的准确时间依赖时间估计，从而直接测量其范围，从而直接测量：Maxwell率在驱动器上的范围范围，并在驱动范围范围内，并在驱动器上范围范围。推断的波动统计数据对磁盘层层边界上的水力稳定性物理产生了影响，并寻找来自低质量X射线二进制的连续重力辐射。
X-ray flux and pulse period fluctuations in an accretion-powered pulsar convey important information about the disk-magnetosphere interaction. It is shown that simultaneous flux and period measurements can be analysed with a Kalman filter based on the standard magnetocentrifugal accretion torque to generate accurate time-dependent estimates of three hidden state variables, which fluctuate stochastically and cannot be measured directly: the mass accretion rate, the Maxwell stress at the disk-magnetosphere boundary, and the radiative efficiency of accretion onto the stellar surface. The inferred fluctuation statistics carry implications for the physics of hydromagnetic instabilities at the disk-magnetosphere boundary and searches for continuous gravitational radiation from low-mass X-ray binaries.
