Abstract:
The asteroseismic and planetary studies, like all research related to
stars, need precise and accurate stellar atmospheric parameters as
input. We aim at deriving the effective temperature (Teff), the
surface gravity (logg), the metallicity ([Fe/H]), the projected
rotational velocity (vsini) and the MK type for 169 F-, G-, K- and
M-type Kepler targets which were observed spectroscopically from the
ground with five different instruments. We use two different
spectroscopic methods to analyse 189 high-resolution,
high-signal-to-noise spectra acquired for the 169 stars. For 67 stars,
the spectroscopic atmospheric parameters are derived for the first
time. KIC 9693187 and 11179629 are discovered to be double-lined
spectroscopic binary systems. The results obtained for those stars for
which independent determinations of the atmospheric parameters are
available in the literature are used for a comparative analysis. As a
result, we show that for solar-type stars the accuracy of present
determinations of atmospheric parameters is ±150K in Teff,
±0.15dex in [Fe/H] and ±0.3dex in logg. Finally, we confirm that
the curve-of-growth analysis and the method of spectral synthesis
yield systematically different atmospheric parameters when they are
applied to stars hotter than 6000K.
Description:
Our programme stars were observed with five different instruments. All
