Thermal generation of the magnetic field in the surface layers of massive stars
arXiv:1709.02239 · doi:10.1093/mnrasl/slx127
Abstract
A new magnetic field-generation mechanism based on the Nernst effect is considered in hot massive stars. This mechanism can operate in the upper atmospheres of O and B stars where departures from the LTE form a region with the inverse temperature gradient.
