Part of the Lecture Notes in Physics book series (LNP, volume 193)


The excitation mechanisms producing the strong S I lines observed in the EUV spectra of late-type giants are discussed. For the case of 8 Gru it is shown that the broad H Ly-e line plays an important role in producing the observed multiplets.
