Scientific paper

We study the influence of Stark broadening effect on Si I lines in the roAp 10 Aql star, where the lines are asymmetrical and shifted. First we have calculated Stark broadening parameters using by the semi-classical method for two Si I lines: 6142.48 Å and 6155.13 Å. We have adopted SYNTH code to include into account both Stark width and shift for these lines. From comparison of our calculation data with observations we found that Stark broadening plus stratification effect can explain the width and the asymmetry of the Si I lines in the atmosphere of roAp 10 Aql star.
