Back on your GBE blog, someone posted a comment about cinstant density being a mistaken assumpation. Again I not too sure if we can use density as a constant factor in the GBE formulae from the way it looks like.

You are assuming constant density.

That is an highly inaccurate assumption.

34% of the sun's mass is lies within .2 soalr radii of the center.

And almost half of it lies wihtin .25 radii.

This means that the core alone has a GBE higher than that of your estimates.

So your value for the Sun is wrong.

Use the original value.

It gets even more eggrius when you conside large stars, as the cores get heaveir and denser.

Here's something that should help.

https://en.wikipedia.org/wiki/Virial_theorem

States that the thermal energy of a star = half it's GBE.

Large stars have much hotter and heavier cores then that of the sun.

And that is where most of a stars thermal energy resides.
