Sun shining and spotting

Sunspot activities demonstrate a normally suppressed regenerative trait of stellar plasma fusion: Plasma fusion leads to production of heat and increased heat increases fusion. Normally, a close regulation of luminosity is provided for our sun at the depths where fusion proceeds.

Temperature of fusing plasma becomes pegged to a single normal value for any given depth where the process occurs. The ideal gas law holds the product of pressure and volume proportional to temperature, and since solar pressure is normally fixed at any given depth, this leaves changes to the volume of fusing plasma alone to vary directly with any change of temperature. Any deviation from normal temperature adjusts the plasma’s volume in the same direction to thereby lift overbearing solar mass in response to overheating, or to permit its descent in response to cooling. Corresponding changes to rate of fusion with temperature circumvent regenerative activity by thus diverting output energy changes into the domain of potential energy instead of heat.

An exception to the constancy of the pressure/depth relationship comes about in the rotational center of swirling masses: The pull of centrifugal force upon such a vortex would reduce solar gas pressure in an extensive column that could penetrate depths given to normal fusion, which might be much more shallow than the central solar core. In consequence, fusion would decelerate to a point of severe underproduction.

In concert with central cooling of a vortex would be effects of a positive pressure gradient surrounding the vortex. At some radius, gas pressure would suffice for fusion that would not be enslaved to the gravitational give and take encountered in normal venues. A sheathing of plasma bearing relatively uncontained rates of fusion would expand into the collapsing center and upwards to break the surface as solar flares. Once the interior collapse subsides as vortex cooling approaches its limit, the sheathing-to-center flow of gasses becomes discontinued to afford normalization toward equilibrium.

A simple sun spot would dimple the surface because of the downdraft and be surrounded with superheated flares that would convey a normal excess of surface electrons upwards at such rates that magnetic fields would form and vary to produce the radio interference we hear so much about.
