Anomalous Neutral Hydrogen Column Densities in Local Interstellar Medium Clouds

Analysis of high-resolution spectra of the hydrogen and deuterium Ly α lines provides measurements of interstellar neutral hydrogen column densities N (H i ) to 113 stars within 50 pc of the Sun. Plots of N (H i ) versus distance through the LIC, G, Mic, and other clouds in the local interstellar me...
