It clearly shows that the X-ray emission of HD 191612 is modulated by the 538d period and not the orbital period of 1542d - it is thus not of colliding-wind origin and the phenomenon responsible for the optical changes appears also at work in the high-energy domain.
New findings on the prototypical Of?p stars
For HD 191612, a new XMM-Newton observation clearly shows that its X-ray emission is modulated by the 538d period and not the orbital period - it is thus not of colliding-wind origin: the phenomenon responsible for the optical changes appears also at work in the high-energy domain.
New findings on the prototypical Of?p stars
