H-He EOS quantities for planetary evolution

This repository contains H-He EOSes from Saumon et al. (1995; SCvH), Militzer & Hubbard (2013; MH13), Chabrier et al. (2019; CMS19), Chabrier & Debras (2021; CD21), and Mazevet et al. (2022; MLS22). The CMS and MLS EOSes are supplemented by the work of Howard et al. (2023a) to account for the non-ideal entropy and volume interactions they calculated from MH13 and CD21. Moreover, we calculate H-He-Z mixutures using a water EOS from Haldemann et al. (2020), iron, and post-perovskite EOSes from Jisheng Zhang (private communication).

To ease thermodynamic derivative calculations, we have inverted the H-He EOSes to provide several independent axes:

and thus Github's Large File Storage is required.
