Metallic hydrogen - Wikipedia
A diagram of Jupiter showing a model of the planet's interior, with a rocky core overlaid by a deep layer of liquid metallic hydrogen (shown as magenta) and an outer layer predominantly of molecular hydrogen. Jupiter's true interior composition is uncertain.
What is metallic hydrogen, and does it exist at the core of all the …
2018年6月27日 · Metallic hydrogen is conductive, and it’s believed to be largely responsible for the dynamo that powers Jupiter’s and Saturn’s magnetic fields. (Whereas on Earth, that dynamo is powered by...
Researchers unravel more mysteries of metallic hydrogen
2018年7月23日 · Researchers at the the University of Rochester's Laboratory for Laser Energetics created metallic hydrogen in the lab to study Jupiter’s magnetic field. The research has implications in planet formation and evolution, including how planets both inside and outside our solar system form magnetic shields.

2016年6月30日 · We may have glimpsed liquid hydrogen abruptly changing into metallic hydrogen, which is the same stuff in the core of Jupiter. But how and when does this transition from gas to liquid metal occur? How does it behave?
Metallic Hydrogen - an overview | ScienceDirect Topics
Liquid metallic hydrogen in Jupiter and Saturn consists of a dense mixture of ionized protons and electrons at temperatures over about 6000 K. The EOS of liquid metallic hydrogen is understood well theoretically for pressures above about 10 Mbar, but the EOS is not well constrained from 0.5 to 10 Mbar, the transition region.
What in the World Is Metallic Hydrogen? | Space
2018年1月15日 · How can the liquid metallic hydrogen inside Jupiter support the crushing weight of the atmosphere above it? The answer is degeneracy pressure, a quantum mechanical quirk of matter under extreme...
Everything you always wanted to know about metallic hydrogen …
2020年4月23日 · In this article, we provide a critical look at the numerous claims of hydrogen metallization and the current experimental state of affairs.
The Interior of Jupiter - University of Rochester
The intense magnetic field of Jupiter is thought to result from electrical currents in this region of metallic hydrogen that is spinning rapidly and thought to compose 75% of the planet's mass. We are limited in our understanding of Jupiter's interior by the fact that we have little laboratory knowledge of the behavior of hydrogen under such ...
National Ignition Facility reveals how hydrogen becomes metallic …
Swirling dense metallic hydrogen dominates the interiors of Jupiter, Saturn and many extra-solar planets. Building precise models of these giant planets requires an accurate description of the transition of pressurized hydrogen into this metallic substance — …
Metallic Hydrogen at High Pressures and Temperatures in Jupiter ...
Hydrogen becomes metallic much closer to the surface of Jupiter than thought previously, and Jupiter has no core-mantle boundary. These conclusions result from studies into the conductivity of fluid hydrogen at pressures up to 180 GPa and temperatures up to 4000 K, which indicate that there is a continuous transition from a semiconducting to ...
