Why not suppose that the surface of our sun is liquid rock? That would fit better with observed temperatures. The objection to this is that hydrogen is predominant in the specter of light coming from our Sun. But is the predominance of hydrogen in the light specter of the corona necessarily indicative of a liquid hydrogen surface? The corona can reach millions of degrees in temperature. Hydrogen could easily be produced by fission of heavier elements at such temperatures.
Maybe the Sun is liquid rock, and the only reason we see so much hydrogen in its light specter is that hydrogen is produced in its hyper-hot corona.
