摘要：
The equation of state (EOS) of the solar interior is accurately and smoothly determined from ab initio simulations named quantum Langevin molecular dynamics in the pressure range of 58 Mbar <= P <= 4.6 x 10(5) Mbar at the temperature range of 1 eV <= T <= 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.
