Determination of Teff and log g for A0 type stars and its impact on the interpretation of the HR diagram with the HIPPARCOS results
Abstract
The determination of the ``Fundamental Parameters'' Teff and log g for a set of dwarf A0-type stars is discussed in terms of consistency when comparing these values determined through different methods. The position of these stars in the HR diagram are discussed, taking into account the HIPPARCOS data. A large number of binary stars with components of similar spectral types has been found from this spectroscopic survey.
