Interiors of giant planets inside and outside the solar system.
@article{Guillot1999InteriorsOG, title={Interiors of giant planets inside and outside the solar system.}, author={Tristan Guillot}, journal={Science}, year={1999}, volume={286 5437}, pages={ 72-7 } }
An understanding of the structure and composition of the giant planets is rapidly evolving because of (i) high-pressure experiments with the ability to study metallic hydrogen and define the properties of its equation of state and (ii) spectroscopic and in situ measurements made by telescopes and satellites that allow an accurate determination of the chemical composition of the deep atmospheres of the giant planets. However, the total amount of heavy elements that Jupiter, Saturn, Uranus, and…
