Magnetic fields, winds and X-rays of massive stars: A spectropolarimetric survey of the Orion cluster
V. Petit, G. A. Wade, L. Drissen +2
In massive stars, magnetic fields are thought to confine the outflowing radiatively-driven wind, resulting in X-ray emission that is harder, more variable and more efficient than t…

X-ray emission and the incidence of magnetic fields in the massive stars of the Orion Nebula Cluster
V. Petit, G. A. Wade, T. Montmerle +3
Magnetic fields have been frequently invoked as a likely source of variability and confinement of the winds of massive stars. To date, the only magnetic field detected in O-type st…
