Sol’s Photosphere

Have other scientists actually figured out the mystery of Sol’s Photosphere? You know, the reason it gets hotter the further up above the surface you get. Sometimes, up to 400× hotter, like 2MK(?). Then it reaches a point where the temperature drops back down. Was reading something the Original Arakish wrote:

From Notebook Dated 1951:

I have always wondered how our star behaves. Think on this. We know the sun ejects particles constantly. Billions of tons every second. These particles are what creates the “stellar winds” effect. The Winds of Space, Isaac Asimov. Part of the Foundation universe.

This is just a thought I had. Those ejected particles are full of energy. I am speaking about where the surface is more quiescent than at the sun-spots. Not where those mass ejections, prominences occur. Where the particle ejection is a bit thinner. Not so massive. But still millions of tons per second.

Would not those ejected particles be filled with joules, possibly petajoules, of Energy? What is the one thing Energy always becomes? Power. Work. And Power produces HEAT. Additionally, those particles ARE going to collide. Those collisions produce Power, which produces Heat. Is it no wonder the Photosphere is hotter than the sun’s surface?

Now guess how old he was when he wrote this. 10y. He went later to explain the scientists probably already thought of it. Thus, he went no further with this idea.

But think on this. Back then it was a mystery why the Photosphere gets so much hotter than the surface. Perhaps the Original Arakish was onto something. He thought it such a simple concept, he never pursued it. He was sure the scientists of that time already thought it.

And I am fairly certain he was talking about where Sol’s coronasphere looks thus:

Even in this calmer region, the sun still ejects, at minimum, millions of tons of particles per second. In scale, Earth is the size of that small sun-spot in the upper right. Pustules of material bubbling up from inside Sol, flowing out, then sinking in sheets. Some bigger than the Earth. T...H...I...N...K...
