Scientific paper

We compute a set of semi-empirical atmospheric models for a large flare on the dMe star AD Leo, assuming different filling factors. These are the first models computed to match both the continuum observations, and a wide set of chromospheric spectral lines. We found that the models with a filling factor between 1 and 5% give good agreement between the computed and observed spectral features. Since the main differences between the predicted and observed emission are in the continuum above 4500A and in Halpha_, simultaneous observations in these spectral features are needed to better determine the filling factor, and whether the area coverage of the flare depends on height.
