An understanding of the structure and composition of the gas giants (e.g., Jupiter and Saturn), terrestrial exoplanets, and stars is intimately tied to our understanding of the equation of state (EOS) of the elements and compounds that make up these astronomical bodies. An EOS is a mathematical relationship that describes the state of matter (i.e., gas, liquid, or solid) using the material properties of temperature, volume, pressure, and internal energy. The EOS characterizes the properties of a state of matter under a given set of physical conditions. Finally, in addition to constraining the composition of planets and stars, accurate EOS models are important for describing astrophysical impacts (and for designing ways to steer asteroids for planetary defense) and for modeling the performance and predicting the effects of projectiles and explosives.
