Determination of T_eff and log g for A0 type stars and its impact on the interpretation of the HR diagram with the HIPPARCOS results
M. Gerbaldi, R. Faraggiana, R. Burnage +3
The determination of the ``Fundamental Parameters'' T_eff and log g for a set of dwarf A0-type stars is discussed in terms of consistency when comparing these values determined thr…

Absolute magnitudes and kinematics of CP stars from Hipparcos data
A. E. Gomez, X. Luri, V. Sabas +5
The position in the HR diagram and the kinematic characteristics of different kinds of CP stars of the upper main sequence are obtained using the LM method (Luri et al., 1996). Mos…

CP stars: Photometric calibrations of luminosity using Hipparcos data
F. Figueras, X. Luri, A. E. Gomez +7
The application of the Stromgren photometric luminosity calibrations to different types of CP stars is reexamined in the light of the new Hipparcos data. A first attempt is made to…
