The spectrum of the cool R Coronae Borealis variable S Apodis in a deep decline.
GOSWAMI A., RAO N.K., LAMBERT D.L. and SMITH V.V.
Abstract (from CDS):
A high resolution spectrum (5575 - 8875Å) of the cool R Coronae Borealis variable S Apodis in its 1993 deep decline is discussed. Narrow or chromospheric emission lines of Na I, K I, Ca II, and Ba II and broad emission lines of He I 7065Åand Na I D are seen, as expected from published reports of warmer RCBs in decline. The surprise of the S Aps spectrum is the considerable blue shift of the broad emissions component to the Na D lines. The blue shift may result from lines formed in a bipolar flow which is obscured asymmetrically by soot clouds along the line of sight.
