The Solar Corona Heating Problem
In order to solve the problem of the solar corona heating, we must deal with it from visualizing that the Earth in many aspects is still representing a heliella. Astronomers consider that the Earth was stripped off the Sun. Accordingly, it turns out very easy to explain the mystery of the solar corona heating problem. For this purpose, I introduce a new theory composed of the following propositions:
1- The Sun has its own heliomagnetosphere which is a gigantic expandable-contractible magnetosphere.
2- The heliomagnetosphere is stratified.
3- In the core of the Sun not only nuclear fusion reactions occur, but thermonuclear reactions are also taking place.
4- Field-aligned Birkeland currents make closed electric circuits between the Sun's core and the heliomagnetospheric layars to transfer the energized charged particles from the core so as to supply the heliomagnetosphere with the electric power needed to drive continuous, very strong, heat-EUV-X-rays-releasing electric discharges.
5- Owing to the dipolar nature of the solar magnetic field, the field-aligned Birkeland currents in the photosphere are greatly weaker than their counterparts in the corona.
6- The resistivity of the coronal plasma and other constituents obliges the field-aligned Birkeland currents, solar polar electrojets and solar ring current to produce tremendous amounts of thermal energy via Joule-heating.
7- The field-aligned Birkeland currents, solar polar electrojets and solar ring current suffer permanent, dense short-circuiting which causes the occurrence of very strong black discharges that release huge amounts of heat, magnetic energy, EUV spectra and X-rays.
8- The coronal magnetic loops are signatures of the short-circuiting process.
9- The discharge-freed magnetic ropes and strings rearrange while collecting the remnants of the untrapped discharge-freed ions and electrons making relatively small-scale explosive magnetic bottles.
10-The MHD waves, including Alfven's waves, play the role of exploding agents.
11-The photosphere represents the solar analogue of the terrestrial ionosphere.
12-The chromosphere represents the solar analogue of the terrestrial protonosphere.
13-The inner solar corona represents the solar analogue of the inner Van Allen radiation belt.
14-The outer solar corona represents the solar analogue of the outer Van Allen radiation belt.
15-The interplanetary magnetic field-heliomagnetosphere coupling maps in the photosphere.
16-Owing to the dipole nature of the solar magnetic field, at any moment the heliomagnetosphere could be considered of two halves each one of them forms a parabolic converging mirror and enjoys a very high ability of amplification.
17-Each one of the parabolic heliomagnetosphere-made mirror converges at its focus a considerable deal of the EUV light, X-rays and infrared waves whether their origin is from the body of the Sun or from the heliomagnetosphere.
18-The plasma in the huge "focus space" is subjected to the converged spectral energy to the level of acquiring a temperature reaching hundreds of thousands, or even millions degrees C.
19-Convection occurs in the permanently boiling plasma in the space of the focus releasing large, extremely hot bubbles in the form of flux transfer events which distribute the highly heated plasma in other parts of the solar corona.
20- Owing to, first, the nature of the dipolar magnetic field inside the photosphere, and second, comparatively high atmospheric pressure in it, the pumped bubbles –magnetic bottles boiling up from the surface – ascend upward across the photosphere almost intact, i.e. without suffering an explosion process, but upon entering the coronal regions, they become under the influence of both relatively low atmospheric pressure and effective exploding agents. Therefore, these magnetic bubbles expand and explode releasing great amounts of heat, EUV radiation, X-rays and free magnetic power.
