Astronomers observe the awakening of a Be/X-ray binary

Using ESA's XMM-Newton space telescope, astronomers have spotted bright X-ray outbursts emitted by a Be/X-ray binary known as A0538−66. The discovery marks the ending of an over three-decade-long period of quiescence of this system. The finding is detailed in a paper published July 18 on arXiv.org.
