Relation between Light Weakening and Equivalent Widths of Circumstellar NaI D-Lines in Stars with R CRB-Type Variability

Relation between Light Weakening and Equivalent Widths of Circumstellar NaI D-Lines in Stars with R CRB-Type Variability

High-resolution spectra in the NaI D-line region for tar­get stars with R Coronae Borealis type variability are analyzed. Two types of relations between light weakening and equivalent widths of circumstellar lines are found, one of them being considerably different from a similar relation for the in...
