Chapter 2. Hypothesis of origin of planetary system (part 1)

Thus we see, the radial thermoelectron current essentially complicates the protostellar structure. As a result of structurisation, the core and thermoconvection region become compact and gain the additional vacuum thermoinsulating layer, and the exterior cocoon strips off the thermoconvection region and compacts into some quite dense envelope that thickens at the equator. Indeed, this structure will not remain constant in the course of star evolution (we will show it below), but at the moment we are interesting just in the initial stage and its processes.

When the magnetic fields of electron circulation currents mutually orient and uncoordinated mechanical rotation moments of contours transform into the common rotation momentum of the star, there will form the magnetic field of star. As we already said, it is directed in the external field, and its intensity will be initially determined by the intensity of circulation currents. To draw the pattern of this field, we should note that the circulation current of the exterior envelope defined by negatively charged ions and the current in the core defined by positively charged ions flow in one direction. This can be modelled by two ring turns nested one into another, if in the exterior turn the current is carried by negative charges, and in the interior turn - by positive charges (see Fig. 2.19).

According to this graphical construction, in the equatorial region between the core and envelope, magnetic fields will add and produce highly heterogeneous in radius magnetic field with the maximum in the vicinity of core. And in the regions of poles, the magnetic fields will subtract. This will cause the peculiar reduction of magnetic field of core at the poles to the very core (the region in which the influence of magnetic field of core is sensible will reduce), so above the poles there will appear the areas with negligibly small strength of magnetic field.
