Using molecular dynamics simulations, we perform the first direct tests
of three proposed models for the pair correlation functions of strongly
coupled plasmas with species of unequal temperature. The models are all
extensions of the Ornstein-Zernike/hypernetted-chain theory used to good
success for equilibrium plasmas. Each theory is evaluated at several
coupling strengths, temperature ratios, and mass ratios for a model
plasma in which the electrons are positively charged. We show that the
model proposed by Seuferling et al. **Phys. Rev. A 40, 323 (1989)** agrees
well with molecular dynamics over a wide range of mass and temperature
ratios, as well as over a range of coupling strength similar to that of
the equilibrium hypernetted-chain (HNC) theory. The SVT model also
correctly predicts the strength of interspecies correlations and
exhibits physically reasonable long-wavelength limits of the static
structure factors. Comparisons of the SVT model with the Yukawa one-
component plasma (YOCP) model are used to show that ion-ion pair
correlations are well described by the YOCP model up to Gamma(e)
approximate to 1, beyond which it rapidly breaks down. Published by AIP
