摘要:

我们已经监测了41 Be/X射线双星系统的小麦哲伦云超过9年使用PCA-RXTE数据从每周的调查计划。对由此产生的光变曲线进行了分析,以寻找轨道调制,结果确认和完善了10个已知的轨道星历,并确定了10个新的轨道星历。首次提供了大量的X射线轨道剖面图,在很大范围的轨道周期内显示出类似的特征。最后,发现三个样本:SXP 46.4、SXP 89.0和SXP 165分别是SXP 46.6、SXP 91.1和SXP 169的错误识别。

英文摘要:

We have monitored 41 Be/X-ray binary systems in the Small Magellanic Cloud over ~9 years using PCA-RXTE data from a weekly survey program. The resulting light curves were analysed in search of orbital modulations with the result that 10 known orbital ephemerides were confirmed and refined, while 10 new ones where determined. A large number of X-ray orbital profiles are presented for the first time, showing similar characteristics over a wide range of orbital periods. Lastly, three pulsars: SXP46.4, SXP89.0 and SXP165 were found to be misidentifications of SXP46.6, SXP91.1 and SXP169, respectively.
