Sj. Adelman, Elemental abundance analyses with DAO spectrograms - XXII. The B9-A3 starslambda Ursae Majoris, 59 Herculis, 14 Cygni and 29 Cygni, M NOT R AST, 310(1), 1999, pp. 146-156
Elemental abundances of the moderately rotating B9-A3 stars lambda UMa, 59
Her, 14 Cyg and 29 Cyg have been derived in a consistent manner with previo
us studies of this series from spectrograms obtained with Reticon and CCD d
etectors. The derived elemental abundances show that lambda UMa is a mild A
m star, while 59 Her is slightly metal-rich. Although 14 Cyg has values clo
ser to solar than these stars, its subsolar Ca and Sc abundances indicate t
hat it might be the hottest known hot-Am star. 29 Cyg is a metal-poor lambd
a Boo star.
