Abstract:
This series of high quality elemental abundance analyses of mostly
Main Sequence normal and peculiar B, A, and F stars defines their
properties and provides data for the comparison with analyses of
somewhat similar stars and with theoretical predictions. Most use high
dispersion and high S/N (greater than or equal to 200) spectrograms
obtained with CCD detectors at the long camera of the 1.22-m Dominion
Astrophysical Observatory telescope's coude spectrograph. Here we
expand the range of stars examined to include two relatively quiescent
F supergiants. nu Her (F2 II) and 41 Cyg (F5 Ib-II) are analyzed as
consistently as possible with previous studies. These LTE fine
analyses use the ATLAS9 and the WIDTH9 programs of R.L. Kurucz. High
signal-to-noise spectrograms and high quality atomic data were
employed. The derived values of these photometrically constant stars
are somewhat different with the abundances of nu Her being somewhat
metal-poor and those of 41 Cyg being crudely solar-like. Our analyses
indicate that the basic results of Luck and Wepfer who also studied nu
Her and 41 Cyg are not likely to be significantly changed by new
studies of all their stars.
