An analysis of the diffuse interstellar cloud complex in front of HD 179406 (20 Aql) was complemented. Along this sight line, multispectral absorption- and emission-line studies have uncovered at least three distinct velocity components due to individual clouds. A dominant velocity component is seen in both the absorption and emission-line data sets at 3 ± 1 km/s. We believe that the cloud associated with this velocity component is responsible for most of the atomic and all of the molecular gas… CONTINUE READING
