X-ray variability in 4U 1636-53

We have studied the rapid X-ray time variability in 149 pointed observations with the Rossi X-Ray Timing Explorer (RXTE)'s Proportional Counter Array of the atoll source 4U...我们在针对礁状X射线源（atoll source）4U……的149次指向观测中，利用罗西X射线计时探测器（Rossi X-Ray Timing Explorer, RXTE）的正比计数器阵列（Proportional Counter Array, PCA），对该源的快速X射线时变特性展开了研究。
