Temperatures inside a Star

Everything I've seen so far just says things like 'core temperature 50 million degrees' (they don't even make the distinction between K & C at those orders of magnitude).

oops. Wrong thread.

Kelvin

The inside of a star must fuse its heaviest elements into heavier elements. So expect the core to be 10 - 50 million Kelvin, depending if you're fusing hydrogen, helium or something alot heavier...

Now above the core - say 1/3 of the way out until almost the surface, you have a convection zone, that probably decreases in temperature down to a few thousand Kelvin at the surface. Becuase of the tremendous pressures, electrical and magnetic forces and turbulence in this section radiation from the core takes about a million years to actually reach the surface (which is a few light seconds from the core). Prominences that burst from the core and arc around the Sun generally have temperatures in the low hundreds of thousands of Kelvin.

Finally super novae have temperatures well into the hundreds of millions of degrees Kelvin, and are the only ways elements heavier than iron - like gold - can be produced. So funny how alot of jewelry worn today came from some Sun's explosion!

Hope that all helps.
