Abstract
We present simplified models for the region where Lα is formed, in the boundary between prominences and corona. The models were calculated by solving the radiation transfer in the line and the energy equation considering conductive flux. We calculate the absolute intensities and profiles of the Lα line given by the models, and compare them with observed values. From the comparison there results that temperature gradient starts increasing in the region of formation of Lyman continuum and reaches a steep gradient in the region where the central core of Lα is formed. We find general agreement and we show the influence of the different parameters on models and on the emerging intensities.
