Abstract

We estimate the magnetic field distribution of the decretion disk of the \(\gamma\) Cas type star HD 110432 using the planar approximation developed for accretion disks. This is based on the assumption about the presence of frequent fast X-ray flares on the star, during which matter is injected into the disk. These flares are found in the X-ray light curves. The maximum value of the magnetic field strength of the disk is shown to have a value of \(10^{-1}\) G.
