Summary
Abstract
In the past decade, measurements of the properties of H2 and He systems at very high pressures have made great progress, now reaching density at the limit of the plasma phase transition of hydrogen. The potentialities and limits of static and dynamic methods will be reviewed. Then, a survey of the major experimental results is presented. It is the intention of this article to show how these measurements can bring information to model low-mass astrophysical objects. Three levels of usefulness are distinguished on selected examples: data for codes of planetary interiors, constraints for theoretical descriptions of dense matter, observations of unsuspected properties at very high density.
Abstract
De grands progrés ont été faits ces dix dernières années dans la mesure des propriétés des systèmes d'H2 et d'He sous très fortes pressions. Des densités à la limite de la transition de phase plasma de l'hydrogène peuvent maintenant être obtenues en laboratoire. Les possibilités et limites des méthodes dynamiques et statiques seront tout d'abord discutées. Ensuite, les principaux résultats expérimentaux seront présentés. Le but de cet article est de montrer comment ces études peuvent être utiles à la modélisation des intérieurs planétaires. Trois niveaux d'application seront dégagés: données pour les codes de structures internes; contraintes pour valider les descriptions théoriques; mise en évidence à très haute densité de comportements inhabituels.
