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.
