Results of the 11-year programme for spectrophotometry of selected Fraunhofer line profiles. Motions in the solar atmosphere.
Abstract
The observational results of an 11-year spectrophotometric survey of selected Fraunhofer lines showing the independence of the line-profile parameters on the phase of the cycle were given earlier. In the course of the investigation the temperature sensitive line C I 5380.322 Å, the so called 7 "magnetic" lines and a faint, but free from blends, Fe II 6084.106 Å line were introduced in the observational programme. Here the authors give the results of the spectrophotometric study of these lines. Particular attention is paid to the asymmetry of the lines. The reduction of their profiles using the new method leads to a new picture of statistically large-scale moving photospheric formations. The statistical role of the oversheets in granules and chromospheric "rain" is evaluated. Some features of the model of the line formation of the temperature and magnetic sensitive lines are given.
