Quantum Langevin molecular dynamics determination of the solar-interior equation of state

Abstract

The equation of state (EOS) of the solar interior is accurately and smoothly determined from \textit{ab initio} simulations named quantum Langevin molecular dynamics (QLMD) in the pressure range of $58\le P\le 4.6\times 10^5$ Mbar at the temperature range of $1\le T\le 1500$ eV. The central pressure is calculated, and compared with other models. The effect of heavy elements such as carbon and oxygen on the EOS is also discussed.
