SiriusMrE - I agree the standard model of how our sun operates is not entirely correct - but it is not as far off as you seem to think either.<br /><br />Our sun is indeed electric, as is our universe.<br /><br />Our sun is also dominated by nuclear fusion, also a very important factor in our universe.<br /><br />It is not a case of our sun either being nuclear or electric.<br /><br />Our sun is both.<br /><br />The solar corona is indeed way much hotter than the solar surface.<br /><br />Likewise in our universe the IGM, intergalactic medium, is way much hotter than the CMBR, the cosmic microwave background radiation - incredibly hotter.<br /><br />Both phenomena (real natural scientific phonomena, btw) are caused by ionization and magnetism.<br /><br />However, nuclear fusion is behind the cause of the ionization.<br /><br />For our sun, it is nuclear fusion of hydrogen into helium, with the resulting neutrino flux (and apparently spontaneous oscillation between the 3 types of neutrinos).<br /><br />For our universe astronomers are not quite sure but suspect supernovae as the cause of the extreme heat and ionization.<br /><br />Ions in motion cause magnetic fields.<br /><br />And this is where I believe the standard model of stellar evolution does not apply completely to our sun - i.e. the standard assumption of zero mixing from core to surface.<br /><br />The solar corona is powered by magnetic fields from deep within the sun, in a sort of dynamo caused by ions in motion.<br /><br />This motion is probably in part caused by convection from heat from the core - there is observational evidence that these magnetic fields float from core to surface - though we still have much to learn.<br /><br />Here is one simple quote from some years ago concerning the observational evidence:<br /><br />"Dr. Bernard Durney, a research director, graciously offered to answer some questions about the sun. He explained that he is working in the field of solar seismology. We needed an explanation of what that meant.
