The spectrum near maximum light of the unusal r coronae Borealis variable DY Persei.
KEENAN P.C. and BARNBAUM C.
Abstract (from CDS):
DY Per was confirmed photometrically as an R CrB variable by Alksnis in 1994. Spectra near maximum light show the high-speed ejection of matter (sodium at -174 km/sec in DY Per) characteristic of many of these variable stars. Moderate hydrogen deficiency may also be present. DY Per is remarkable in having a temperature many hundreds of degrees lower than most of the R CrB variables. It is unusual also in not showing clear spectroscopic evidence of high luminosity.
