Abstract:
Parameters and abundances for 451 stars of spectral types F, G, and K
of luminosity classes I and II have been derived. Absolute magnitudes
and E(B-V) have been derived for the warmer stars in order to
investigate the galactic abundance gradient. The value found here:
d[Fe/H]/dR~-0.06dex/kpc, agrees well with previous determinations.
Stellar evolution indicators have also been investigated with the
derived C/O ratios indicating that standard CN processing has been
operating. Perhaps the most surprising result found in these
supposedly relatively young intermediate-mass stars is that both
[O/Fe] and [C/Fe] show a correlation with [Fe/H] much the same as
found in older populations. While the stars were selected based on
luminosity class, there does exist a significant [Fe/H] range in the
sample. The likely explanation of this is that there is a significant
range in age in the sample; that is, some of the sample are low-mass
red-giant stars with types that place them within the selection
criteria.
Description:
The primary source of observational data for this study is a set of
high signal-to-noise ratio (S/N) spectra obtained during numerous
observing runs between 1997 and 2010 at McDonald Observatory using the
2.1m Struve Telescope and the Sandiford Cassegrain Echelle
Spectrograph. The spectra continuously cover a wavelength range from
about 484 to 700nm, with a resolving power of about 60000.
High S/N spectra were obtained during the period 2008 August-2010
November using the Hobbly-Eberly Telescope (HET) and its
High-Resolution Spectrograph (HRS). These spectra cover a continuous
wavelength range from 440 to 785nm with a resolving power of about
30000.
The ESO Archive was used to obtain Max-Planck-Gesellschaft (MPG)
telescope/FEROS spectrograph data on 133 stars including a number of
Cepheids not included in Luck et al. (2011, cat. J/AJ/142/51). The
spectra cover a continuous wavelength range from 400 to 785nm with a
resolving power of about 48000.
A further 134 spectra were obtained from the ELODIE Archive. These
echelle spectra are fully processed through order co-addition with a
continuous wavelength span from about 400 to 680nm and a resolution of
42000.
