Observable Effects of B fields on the Winds and Envelopes of Hot Stars
Joseph P. Cassinelli
Magnetic fields on hot stars can produce a variety of interesting effects on the velocity, density, and temperature structure in the winds from the stars. The fields can produce a…

Determination of Magnetic Fields in the Winds from Hot Stars Using the Hanle Effect
Joseph P. Cassinelli, Kenneth H. Nordsieck, Richard Ignace
Resonance lines that are sensitive to the Hanle effect are prominent in the UV spectra of early-type stars. To understand the differences from the solar application of the Hanle ef…

EUV/X-ray Emission and the Thermal and Ionization Structure of B Star Winds
David H. Cohen, Joseph P. Cassinelli, Joseph J. MacFarlane +1
We discuss the EUV and X-ray properties of B stars, focusing on CMa (B2 II) which is the only star with both emission lines and a photospheric continuum detected with EUVE. We…
