Scientific paper

The use of acoustic waves to obtain realistic profiles for the solar Mg II resonance lines without using ad hoc parameters such as micro- and macroturbulence is studied. One-dimensional models are used which treat the waves nonlinearly. Line profiles are calculated with radiative transfer equations which are expressed in the observer's frame, accounting for the effects of partial redistribution in frequency and direction. It is found that the model can reproduce the observed k3 reversal and the global intensity. It is suggested that two-dimensional computations are necessary to reproduce the observed peak-to-peak distance.
