Formation of resonance spectral line profiles in stellar wind: Theory and observations

Sapar, L.; Sapar, A.

The theory of the formation of resonance spectral line profiles in the stellar wind of hot stars has been elaborated taking into account the presence of microturbulent motions. In this case the local frequency redistribution in the line profile function is incomplete. This circumstance generates dominating backscattering of photons and drastic cha…
