Special Features of the Magnetic Field Structure of the He-r Star HD 37479 \(\boldsymbol{\sigma}\)Ori E

Abstract

The structure of the magnetic field of HD 37479 corresponds to the structure of a dipole displaced along the axis by a significant value \(\Delta a=0.2R_{*}\) and across the axis by the value \(\Delta a=0.05R_{*}\). As a result, the magnetic field is distributed extremely unevenly over the stellar surface. The maximum values of the average surface magnetic field are equal to \(B_{s}=+2591\) and \(-7486\) G. It is in these areas that the maximum wind occurs, and also in approximately these same areas the maximum helium abundance is observed. A cloud of rarefied gas extends along the magnetic equator, in which H\(\alpha\) emission lines are formed.
