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…

Magnetic topologies of the Herbig Ae/Be stars
E. Alecian, G. A. Wade, C. Catala +9
Our recent discoveries of magnetic fields in a small number of Herbig Ae/Be (HAeBe) stars, the evolutionary progenitors of main sequence A/B stars, raise new questions about the or…
