Evaluation of astrophysically useful parameters for strontium monohydride and deuteride
The Franck-Condon factors and r-centroids which are very closely related to transition probabilities, have been evaluated by the more reliable numerical integration procedure for the band systems B2Σ-X2Σ, C2Σ-X2Σ and F2Σ-X2Σ of astrophysical molecules strontium monohydride and strontium deuteride us...

| Summary: | The Franck-Condon factors and r-centroids which are very closely related to transition probabilities, have been evaluated by the more reliable numerical integration procedure for the band systems B2Σ-X2Σ, C2Σ-X2Σ and F2Σ-X2Σ of astrophysical molecules strontium monohydride and strontium deuteride using an adequate potential. The Franck-Condon factors are more intense, particularly for the Δν = 0 bands, for all the systems examined here. Thus the bands of the molecules are expected to be present in sunspot spectra, SC-stars, cool M-giant stars and other prominent astrophysical sources. |
