# Complete Sun altitude-temperature graph?

I found a bunch of partial graphs.

For interior: src

For surface: src

The closest thing I could find that would cover more than innermost piece of corona is for sigma binaries. As if solar corona outer reaches were a taboo not to be spoken of, the graphs for it are always cut off way before its peak, never mind fade region. src

(of course I'm also getting temperature graphs up to Pluto distance...)

Does anyone have a single complete graph that shows temperature of the Sun from the very middle, to somewhere far out in the corona? One that would show where the peaks appear relative to each other, what size are the regions of temperature to each other - not a tiny slice but a more general image?

• I would doubt that such a thing exists, because the interior and the atmosphere of the sun are each usually generated by very different codes working on different timescales etc., and the density of the solar wind out to Pluto can actually be measured. So I don't know if anyone ever bothered to match this, just to get a huge temperature graph out of this. – AtmosphericPrisonEscape May 30 '17 at 13:07
• @AtmosphericPrisonEscape: I don't know if it would be so huge, going to, say, 6 solar radii instead of one. – SF. May 30 '17 at 13:28
• AtmosphericPrisonEscape is correct. The temperature profiles in these two regions are made by drastically different models. There would be no single model which would give you the temperature profile from the core to 6 solar radii. At best, you might just have to stitch the models together, but realize they come with different uncertainties and assumptions so it may not be valid to do so. – zephyr May 30 '17 at 13:32
• @zephyr: What about a graph from 1 or 1.5 to 6 solar radii? 'cause I'm really at loss as to total absence of graphs containing the corona temperature layout. – SF. May 30 '17 at 13:40
• I think the reason you're having a hard time finding such a graph is because it is really hard to produce. For one thing, what type of temperature are you talking about? The effective temperature? The excitation temperature? The ionization temperature? The kinetic temperature? The color temperature? After a few thousand km from the surface, the atmosphere of the Sun is nothing but a relatively diffuse plasma and the notion of temperature is tricky. What's more, any models one might use to produce such a graph would rely on knowing a lot of uncertain information. – zephyr May 30 '17 at 14:03
