Expérimental
Thanks to the development of powerful pulsed devices, such as high energy lasers, today it is possible to bring matter to extremely high temperature (~10^4K) and pressure (~10^6 bar) conditions, similar to those found in planets’ interiors. Knowing the behaviour of matter at these extreme states is of primary importance to unveil the internal structure of planets. This is not only of interest in its own, but it is also critical to understand the solar system's history, formation, and evolution.
