Abstract We describe a method for solving the line-transfer equations for a two-component atmosphere consisting of an array of columns, characterized by a particular variation of temperature with height, which are embedded in a medium in which the temperature is a different function of height. Radiative interaction between the two regions is taken into account, and the opacity is allowed to vary arbitrarily with depth. Some calculations that correspond to the solar Ca K-line are described.

Initial modeling of TX Pscs chromosphere is presented. Simple LTE flux calculations can be made to reproduce the IUE spectrum. Non-LTE effects of hydrogen decrease the electron density in the outer layers as compared to LTE.
