- Title
Planetary science: Soft metals.
- Abstract
The article provides information on a study conducted by Lars Stixrude of University College London in England and Raymond Jeanloz of the University of California in Berkeley focusing on metallic helium. It mentions that the two researchers calculated the amount of squeezing needed in helium when its hot and cold. It suggests that 30 million atmospheres turns helium metallic at about 20,000 kelvin which means that metallic helium should mix readily with metallic hydrogen in the fluid interiors of Jupiter and Saturn. The result supports the idea that a layer of liquid and electrically insulating helium, floating on metallic hydrogen could possibly produce helium rain in the dense atmospheres of these planets.
