Scientific paper
The contribution of interstellar matter to line widths of emission Ca II H and K lines in spectra of late-type stars is considered. The authors found that interstellar matter contribute to line widths of late-type Ca II H and K lines, and that in the physical interpretation of the Wilson-Bappu effect as well as in studies of stellar chromospheres in these lines, this effect should be taken into account.
