Observational constraints on the dense plasma of the solar interior

Professor Werner Dappen
University of Southern California

Helioseismology has become a very successful diagnosis of the equation of state. Although the gas in the solar interior is only weakly coupled and weakly degenerate, the great observational accuracy of the helioseismological measurements puts strong constraints on the nonideal part of the equation of state. For solar and stellar modelling, a high-quality equation of state is crucial. But the inverse is also true: the astrophysical data put constraints on the physical formalisms, thus making the Sun and the stars laboratories for plasma physics. I will review plasma physics issues, but also mention other breakthroughs in solar physics, such as with neutrinos.
