Liquid Metallic Hydrogen and Solar Physics — •Alexander Unzicker — Pestalozzi-Gymnasium München

The metallic state of hydrogen, postulated by Wigner and Huntigton in 1935, presents both experimental and theoretical challenges and is a topical research field in condensed matter physics. In particluar, it has been hypothesized that liquid metallic hydrogen may be metastable at normal conditions. Focussing on the unique character of hydrogen as 'zeroth' alkali metal, the ranges of possible pressures and temperatures are discussed.

The existence of a metastable state would have profound consequences for understanding of the sun, since a series of observations supports the idea that the sun's surface is liquid. These arguments have been advanced in much detail by Pierre-Marie Robitaille, a renowned radiologist, but have received little attention in the solar physics commmunity so far.

The talk also tries to enhance the communication across different fields of physics that is sometimes necessary when a long established paradigm - in this case the standard solar model - is in trouble. Disussions are particlularly welcome.
