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…

Oxygen-rich Mira variables: near-infrared luminosity calibrations. Populations and period-luminosity relations
R. Alvarez, M-O. Mennessier, D. Barthes +2
HIPPARCOS astrometric and kinematical data of oxygen-rich Mira variables are used to calibrate absolute near-infrared magnitudes and kinematic parameters. Two sets of near-infrared…
