Optical and X-ray study of the peculiar high-mass X-ray binary XMMU J010331.7โ730144
Optical and X-ray study of the peculiar high-mass X-ray binary XMMU J010331.7โ730144
For a long time XMMU J010331.7-730144 was proposed as a high-mass X-ray binary candidate based on its X-ray properties, however, its optical behaviour was unclear - in particular previous observations did not reveal key Balmer emission lines. In this paper we report on optical and X-ray variability of the system. โฆ
