A note on the calibration of effective temperatures.
Abstract
It is pointed out that the discrepancy in the derived chemical compositions between B-A1 stars and stars of later spectral types can be remvoed if another T-sub-eff calibration is applied for A and F type stars than the one usually used. The effective temperatures of the components of YZ Cas and TY Pyx were studied closely. It would be interesting to find detached systems at high galactic latitudes with masses between 2.2 and 1 solar masses that feature a total eclipse. In such cases it should be possible to make reliable determinations of various T-sub-eff relations (solar mass ratio, log g, abundance). EK Cep could be a candidate (Tompkin, 1983), although its galactic is +12 degrees.
