Scientific paper

Models are presented for the two continuum-emitting kernels observed in the white-light flare (WLF) of June 15, 1982. They are the first semiempirical models of a WLF which are consistent not only with observations of the continuum emission level but also with a set of spectral lines having heights of formation which span the chromosphere and upper photosphere. It is shown that the models are not compatible with the hypothesis that the continuum emission is caused by enhanced Balmer and Paschen hydrogen continua, and they present strong evidence instead that the emission is of photospheric origin and that its source is due to H(-). The observation and the models derived from them show that white-light emission can occur in areas of the active region where there is no chromospheric emission and in particular no H-alpha emission. This fact seems to rule out the viability of downward transport mechanisms as the source of the energy required for the WLF.
