标题： Hard X-ray lightcurves of High Mass X-ray binaries

摘要： 利用现在从CGRO上的Burst And Transient Source Experiment (BATSE)获得的9年连续数据，我们测量了8个高质量X射线双星（HMXB）的轨道周期并生成了折叠光变曲线。由于数据集的长度，我们的确定基于比以前研究更多的双星轨道。因此，我们的源检测具有很高的统计显著性，并且能够跟踪X射线输出的长期趋势。特别是我们关注两个系统：A0538-668和EXO2030+375，两者都是表现出I型爆发的HMXB。 显示英文摘要

摘要： Using the 9 years of continuous data now available from the Burst And Transient Source Experiment (BATSE) aboard CGRO, we have measured orbital periods and produced folded lightcurves for 8 High Mass X-ray Binaries (HMXB). Given the length of the datasets, our determinations are based on many more binary orbits than previous investigations. Thus our source detections have high statistical significance and we are able to follow long-term trends in X-ray output. In particular we focus on two systems: A0538-668 and EXO2030+375 both HMXBs exhibiting Type I outbursts.
