To analyze the internal structure of a compressed atom or ion immersed in dense plasmas, many theoretical schemes, such as orthodox Hartree-Fock-Slater method, time-honored statistical theory of atoms and a more systematic density functional theory, have been devised and developed. In this article, we propose the two-temperature model of atoms, composed of an ion core in its ground state ({ital T}=0) and a clad electron gas at finite temperatures ({ital T}{gt}0), the latter being held in thermal equilibrium with a surrounding dense plasma. We analyze the model with recourse to the Thomas-Fermi-Dirac-Weizs{umlt a}cker statistical theory and present several results. Throughout this article, the atomic units are used, unless otherwise specified. {copyright} {ital 1996 American Institute of Physics.}
