| Sumario: | Neutral hydrogen line profiles in the direction of 60 early stars of the Southern hemisphere with interstellar Ca+ and Na° lines have been studied. The comparison of optical and radio observations allowed the existence of several structures with peculiar motions to be inferred, by correlating optical and radio velocities and considering the distance of the coincident components to be not greater than the distance of the star. Then stars were found to have non-coincident optical and radio lines, they were all situated on regions of high absorption. |
