摘要

In Allard and Kielkopf (Allard, N.F., Kielkopf, J.F., 2009. A&A, 493, 1155) we presented a temperature and density dependence of the Lyman-α line wing in DA white dwarfs atmospheres. In that paper, we pointed out that close collisions of many perturbers lead to the formation of a series of satellites in the far red wing of Lyman-α. Our study was restricted to H-H collisions but other perturbing species are also present in cool white dwarf atmospheres. We have now included the effects of He on the Lyman-α profile.
