We solve the Ornstein-Zernike equation within the hypernetted chain approximation for dense multi-component plasmas using effective pair potentials. The method is used to study structural properties of plasmas, for instance in order to explain and predict X-ray Thomson scattering spectra. Corresponding experiments are performed at free electron lasers such as FLASH Hamburg and LCLS Stanford, or at facilities using energetic optical lasers such as Omega in Rochester and Janus in Livermore. Results for pair distribution functions and static structure factors for dense hydrogen, beryllium, carbon and carbonhydride plasmas are presented. Furthermore, calculations for non-equilibrium two-temperature plasmas are performed as well, which are relevant for laserplasma interaction and relaxation phenomena on short time scales. We propose a consistent treatment for the electron-ion coupling term which leads to a more realistic description of correlation effects. ((c) 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
