摘要:

本文介绍了小麦哲伦云中一个新发现的X射线瞬变系统的光学和X射线观测结果。这些数据揭示了许多以前未知的X射线探测这个系统和明确的证据,为49.995天的双星周期。此外,光学光度测量显示在双星周期重复爆发的特征,这很可能表明中子星与Be星周围的星周盘相互作用。

英文摘要:

Optical and X-ray observations are presented here of a newly reported X-ray transient system in the Small Magellanic Cloud. The data reveal many previously unknown X-ray detections of this system and clear evidence for a 49.995d binary period. In addition, the optical photometry show recurring outburst features at the binary period which may well be indicative of the neutron star interacting with a circumstellar disk around a Be star.
