The table presented gives the line strength distribution parameters \alpha, \bar{Q}, Q_0 and Thompson scattering mass absorption coefficient \kappa_e. Each of these parameters is given as a function of mass density \rho and temperature T of the gas.

Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current sheet formed in the middle magnetosphere by the wind opening magnetic field l

Building on results from the Magnetism in Massive Stars (MiMeS) project, this paper shows how a two-parameter classification of massive-star magnetospheres in terms of the magnetic wind confinement (which sets the Alfv��n radius RA) and stellar r

Large magnetometric surveys have contributed to the detection of an increasing number of magnetic massive stars, and to the recognition of a population of magnetic massive stellar objects with distinct properties. Among these, NGC 1624-2 possesses th
