Abstract

The scope of asteroseismic studies within the Belgo-Indian Network for Astronomy and astrophysics (BINA) is explored. The main strands of current research in asteroseismology of solar-type stars are outlined. While it is obvious that it would be difficult to match the quality of the space-based seismic data on such stars with ground-based telescopes, the possibility of contribution to supplemental non-seismic data is considered. New calibrations of colour-temperature relations using archival data are presented. It is proposed that with similar calibrations with BINA-based photometric data in the future, it would be possible to provide accurate estimates of effective temperatures of solar-type stars that would be useful in asteroseismology of such stars.

Keywords : asteroseismology, solar-type stars, photometry, colour, effective temperature
