Scientific paper

A model of Jupiter characterized by a hot gaseous interior is analyzed. The internal density and pressure are calculated in terms of Jupiter's radius and mass, the nonuniformity of the planet's internal structure is determined on the basis of observed disk flattening and satellite motion, and accurate values are obtained for the central density and pressure. Assuming a hot interior where internal pressure is a function of the energy of thermal motion and taking into account both gas degeneracy and electrostatic interaction between particles, a central temperature of 165,000 K is computed. This temperature is found to result in a thermal flux from Jupiter's surface whose value is close to that detected during the Pioneer flights. It is concluded that such agreement provides independent confirmation of the 'hot' model's validity and also of the hypothesis that the matter within Jupiter is a gas at the threshold of degeneracy.
