Skye: A Differentiable Equation of State

Understand

Stellar evolution and numerical hydrodynamics simulations depend critically on access to fast, accurate, thermodynamically consistent equations of state.

• We present Skye, a new equation of state for fully-ionized matter.
• Skye includes the effects of positrons, relativity, electron degeneracy, Coulomb interactions, non-linear mixing effects, and quantum corrections.
• Skye determines the point of Coulomb crystallization in a self-consistent manner, accounting for mixing and composition effects automatically.
