Multiple component chromospheric models for AR lacertae

Current models of stellar chromospheres match either the global flux in the far ultraviolet emission lines or the details of a global line profile in order to obtain the atmospheric temperature structure. With this, it has been possible to model the global energy balance and derive a solution to the globally averaged physical properties of stellar chromospheres. However, such one component models do not actually characterize the physical structures which comprise the chromosphere, only the apparent mean structure.
