我们报告了从低质量 X 射线双星 MS 1603.6+2600 (UW CrB) 中发现的几个类光爆发事件。该事件持续几十秒，表现出非常快的上升和缓慢的衰减，并且涉及 2-3 倍的光学增亮。这些耀斑看起来与较低水平的闪烁不同，而是与许多其他中子星低质量 X 射线双星中看到的经过再处理的 I 型 X 射线爆发非常相似。结合之前报道的候选 X 射线爆发，这些证实了 UW CrB 中的致密天体是一颗中子星。我们检查光突发亮度和重复时间，并讨论如何限制系统的性质。我们得出的结论是，源很可能是中等距离的吸积盘日冕源，而不是附近的静止系统或非常远的北斗七星。
We report the discovery of several optical burstlike events from the low-mass X-ray binary MS 1603.6+2600 (UW CrB). The events last for a few tens of seconds, exhibit a very fast rise and slow decay, and involve optical brightening of a factor of 2-3. The flares appear distinct from the lower level flickering and instead strongly resemble reprocessed type I X-ray bursts as seen in a number of other neutron star low-mass X-ray binaries. In conjunction with the previously reported candidate X-ray burst, these confirm that the compact object in UW CrB is a neutron star. We examine the optical burst brightness and recurrence times and discuss how the nature of the system can be constrained. We conclude that the source is most likely an accretion disk corona source at an intermediate distance, rather than a nearby quiescent system or very distant dipper.
