Another one (BH+OB pair) bites the dust

Yael Naze, Gregor Rauw

Most (or possibly all) massive stars reside in multiple systems. From stellar evolution models, numerous systems with an OB star coupled to a black hole would be expected to exist.…

Colliding winds in WR21 and WR31 -- I. The X-ray view

Yael Naze, Gregor Rauw, Rachel Johnson +2

WR21 and WR31 are two WR+O binaries with short periods, quite similar to the case of V444 Cyg. The XMM-Newton observatory has monitored these two objects and clearly revealed phase…

Extreme mass ratios and fast rotation in three massive binaries

Yael Naze, Nikolay Britavskiy, Gregor Rauw +2

The origin of rapid rotation in massive stars remains debated, although binary interactions are now often advocated as a cause. However, the broad and shallow lines in the spectra…

Revisiting the orbital motion of WR 138

Gregor Rauw, Yaël Nazé, Eric Gosset

The optical spectrum of WR 138 exhibits emission lines typical of a WN6o star and absorption lines from a rapidly-rotating OB star. Using a large set of spectroscopic data, we esta…

New insight into the massive eccentric binary HD 165052: self-consistent orbital solution, apsidal motion, and fundamental parameters

Sophie Rosu, Edwin A. Quintero, Gregor Rauw +1

HD165052 is a short-period massive eccentric binary system that undergoes apsidal motion. As the rate of apsidal motion is directly related to the internal structure constants of t…

Diving into the magnetosphere of the Of?p star HD108

Gregor Rauw, Yaël Nazé, Asif ud-Doula +1

We analyse optical and X-ray spectroscopy of the Of?p star HD108, known for its strong dipolar magnetic field and its optical line profile variability with a timescale of $54 \pm 3…
