Equivalent Width of Interstellar Molecular Lines. IV: Analyses of the Line Spectrum of H2 in the Interstellar Spectrum of δ Scorpii
We have made an analysis of the observed equivalent widths of the lines of Lyman and Werner bands by Smith. The H2 column densities of 3×1019 to 1020 and the excitation temperature of 80 to 150 K satisfy the observations. This temperature refers to the kinetic temperature. We have also discussed the importance of getting the excitation temperature from lines of H2 and other heteronuclear diatomic molecules for the same star and from different regions of space.
