New preprint paper by Leif Holmlid:
Condensed Hydrogen Matter H(L), Metallic Hydrogen H(1) and Ultradense Hydrogen H(0) in the Solar System
QuoteAbstract
Ultra-dense hydrogen H(0) is the most stable form of hydrogen that exists. Its properties have been measured and reported in numerous experimental papers. Since it also is the densest material in the Solar system, it is expected that a large inner part of the giant planets is of this type of matter. The density of H(0) agrees with the density of these planets. The well-studied annihilation processes in H(0) release energy at much lower temperatures than those needed for fusion, so they can provide the heat generated in e. g. Jupiter. Since H(0) easily transforms to metallic hydrogen H(1) and superconductive H(l), the magnetic fields of the giant planets can be caused by these fluid conductive materials. The variability of the Great Red Spot on Jupiter (sometimes white, sometimes dark red) can be understood as due to variable stimulated deexcitation of rotational transitions in H(0). These transitions have been studied and resolved in the laboratory. The RF signals from Jupiter agree with rotational transitions in H(l) pairs and in planar H(l) clusters with relatively small l values. Also other bodies in the solar system, in particular asteroids and comets, are proposed to have a similar composition. The IR emission spectra of comets agree with H(l) (Holmlid, Icarus 2006). The explosive behaviour of asteroids and comet nuclei indicates that they contain H(l).
