Description
Recent data from the NASA Kepler mission has provided a big boost to
asteroseismic studies of solar-type stars and red giants. It is now
possible to provide strict constraints to models of such
stars by comparing the observed frequencies with the theoretically
predicted ones. However, the seismic constraints are only useful when
the effective temperature (Teff) and surface metallicity ([Fe/H]) of
the observed stars are accurately known. We propose to use the
telescopes under the BINA collaboration to obtain high resolution
spectroscopy in order to estimate Teff and [Fe/H] of both observed
and future Kepler and TESS targets. The possibility of obtaining a
colour-temperature calibration curve, using photometric observations
with the Devasthal Optical Telescope (DOT) will also be explored.
