Scientific paper

We will observe the Lyman alpha line at 100,000 spectral resolution towards 7 late-type local stars. The purpose is to derive the hydrogen and deuterium column densities and D/H ratios along lines of sight towards nearby stars. High resolution spectra of the MgII and FeII lines will be obtained to help determine the broadening parameter and whether material along these lines of sight has more than one velocity component.
