Hydrogen Lines

We compare infrared hydrogen lines observed with ATMOS with computations for two models of the solar atmosphere, one without and one with a chromosphere. The weaker H I lines are formed in the photosphere. Proper evaluation of Stark broadening is required to reproduce their profiles; the heavy ion contribution is most important. The cores of the stronger lines are sensitive to the structure of the chromosphere, but detailed NLTE modeling is needed for diagnostic applications.

Good Agreement

Abstract The Method of Model Microfields proposed by Brissaud and Frisch is applied to calculate Stark broadened profiles of hydrogen lines in the static ion approximation. Numerical results for L-α, H-α, and H-β are found to be in good agreement with those derived from the unified theory by Vidal, Cooper, and Smith over a wide range of plasma densities and temperatures. This demon­ strates that reliable line profiles may be obtained from the microfield distribution and covariance alone, more complicated statistical features being less important in this context.

The Impact

Abstract The “classical path theory” for the plasma broadening of hydrogen lines calls for a closer examination of the influence of radiator motion on Stark profiles. For a radiator with constant velocity Stark broadening is effected by an anisotropic plasma, and in a frame of reference moving with the emitter the line shape depends not only on the radiator speed but on the direction of emission as well. From this, a somewhat intricate correlation of Stark and Doppler broadening arises which has to be taken into account in the calculation of the full line profile. As an example, broadening by plasma ions is investigated in the impact limit where a distinct dependence of Stark broadening on the emitter velocity is found especially for very heavy, immovable ions.
