Query: Fundamental properties of five Kepler stars using global asteroseismic
  quantities and ground-based observations   We present an asteroseismic study of the solar-like stars KIC 11395018, KIC
10273246, KIC 10920273, KIC 10339342, and KIC 11234888 using short-cadence time
series of more than eight months from the Kepler satellite. For four of these
stars, we derive atmospheric parameters from spectra acquired with the Nordic
Optical Telescope. The global seismic quantities (average large frequency
separation and frequency of maximum power), combined with the atmospheric
parameters, yield the mean density and surface gravity with precisions of 2%
and ~0.03 dex, respectively. We also determine the radius, mass, and age with
precisions of 2-5%, 7-11%, and ~35%, respectively, using grid-based analyses.
We determine asteroseismic distances to these stars with a precision better
than 10%, and constrain the stellar inclination for three of the stars. An Li
abundance analysis yields an independent estimate of the age, but this is
inconsistent with the asteroseismically determined age for one of the stars. We
compare the results from five different grid-based analyses, and we find that
they all provide radius and mass values to within 2.4sigma. The absence of a
metallicity constraint when the average large frequency separation is measured
with a precision of 1% biases the fitted radius and mass for the stars with
non-solar metallicity (metal-rich KIC 11395018 and metal-poor KIC 10273246),
while including a metallicity constraint reduces the uncertainties in both of
these parameters by almost a factor of two. We found that including the average
small frequency separation improves the determination of the age only for KIC
11395018 and KIC 11234888, and for the latter this improvement was due to the
lack of strong atmospheric constraints. (Abridged).
