Thermoelectrokinetic phenomena in the convective plasma zone of the Sun and stars

The study shows that electromagnetic phenomena in the convective plasma zone of the Sun and stars and the local magnetic field near the Sun’s surface are caused not only by the magnetohydrodynamic dynamo mechanism (Krause, Rädler 1980; Moffatt 1978; Morozov 2006), but also by the phenomena that have relatively recently become the focus of research, i. e., thermoelectrokinetic phenomena in the viscous electrically conductive medium in the presence of a temperature gradient (Grabov 2003; 2005a; 2005b; Prigogine, Nicolis 1977). The results of physical modelling and quantitative estimates show that thermoelectrokinetic currents can create primary magnetic fields of approximately B ≅ 103 Gs in the convective plasma zone of the Sun and stars.
