中极TX冕中持续准周期振荡的发现
The Discovery of a Persistent Quasi-Periodic Oscillation in the Intermediate Polar TX Col
摘要：
我们报告的检测~5900秒的准周期变化的广泛测光的TX Col跨越12年。我们讨论五种不同的模型来解释这一时期。我们赞成的机制，准周期性变化的结果，从殴打的开普勒频率的“斑点”轨道外吸积盘的自旋频率，并从调制吸积这些“斑点”发生在一个冲击区附近的磁盘/磁层边界。
英文摘要：
We report on the detection of an ~5900 s quasi-periodic variation in the extensive photometry of TX Col spanning 12 years. We discuss five different models to explain this period. We favour a mechanism where the quasi-periodic variation results from the beating of the Keplerian frequency of the `blobs' orbiting in the outer accretion disc with the spin frequency, and from modulated accretion of these `blobs' taking place in a shocked region near the disc/magnetosphere boundary.
