Hydrogen Stark Broadened Brackett lines

Abstract EN

Stark-broadened lines of the hydrogen Brackett series are computed for the conditions of stellar atmospheres and circumstellar envelopes.

The computation is performed within the Model Microfield Method, which includes the ion dynamic effects and makes the bridge between the impact limit at low density and the static limit at high density and in the line wings.

The computation gives the area normalized line shape, from the line core up to the static line wings.
