The MiMeS Survey of Magnetism in Massive Stars: Introduction and overview
G. A. Wade, C. Neiner, E. Alecian +47
The MiMeS project is a large-scale, high resolution, sensitive spectropolarimetric investigation of the magnetic properties of O and early B type stars. Initiated in 2008 and compl…
Effect of scattering on the transonic solution topology and intrinsic variability of line-driven stellar winds
Jon O. Sundqvist, Stanley P. Owocki
For line-driven winds from hot, luminous OB stars, we examine the subtle but important role of diffuse, scattered radiation in determining both the topology of steady-state solutio…
X-ray emission from the giant magnetosphere of the magnetic O-type star NGC 1624-2
V. Petit, D. H. Cohen, G. A. Wade +7
We observed NGC 1624-2, the O-type star with the largest known magnetic field Bp~20 kG), in X-rays with the ACIS-S camera onboard the Chandra X-ray Observatory. Our two observation…
The changing UV and X-ray properties of the Of?p star CPD -28 2561
Yael Naze, Jon O. Sundqvist, Alex W. Fullerton +4
The Of?p star CPD -28 2561 was monitored at high energies with XMM-Newton and HST. In X-rays, this magnetic oblique rotator displays bright and hard emission that varies by ~55% wi…
Long term variability of Cygnus X-1: VII. Orbital variability of the focussed wind in Cyg X-1 / HDE 226868 system
V. Grinberg, M. A. Leutenegger, N. Hell +8
Binary systems with an accreting compact object are a unique chance to investigate the strong, clumpy, line-driven winds of early type supergiants by using the compact object's X-r…
