Relation between light weakening and equivalent widths of circumstellar NA I d-lines in stars with R crb-type variability.

ROSENBUSH A.E. and BONDAR A.V.

Abstract (from CDS):

High-resolution spectra in the Na I 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 interstellar medium.
