Hyades distance and chemical composition from the competitive use of astrometry, photometry, spectroscopy, and internal structure computation.
Abstract
An analysis of observational astrometric, photometric, spectroscopic data for the Hyades cluster is performed in order to compare Hyades G dwarfs to the sun. Internal structure computations are also used to compare the solar ZAMS with the Hyades ZAMS and to discuss the constraints existing between distance and chemical composition for the cluster.
