Chemical abundance analysis of the Open Clusters Berkeley 32, NGC 752, Hyades and Praesepe
Stars: abundances – Galaxy: disc – Galaxy: open clusters and associations: individual: NGC 752 Hyades Berkeley 32 Preasepe (M 44)

Context. Open clusters are ideal test particles to study the chemical evolution of the Galactic disc. However the existing high-resolution abundance determinations, not only of [Fe/H], but also of oth...
The Solar neighbourhood in angle coordinates: the Hyades moving group
solar neighbourhood – Galaxy: kinematics and dynamics – methods: data analysis
2011/9/29
I investigate the suggestion that the Hyades moving group in the Solar neighbourhood is the result of a recent inner Lindblad resonance. I use dynamical "torus" models of the Galaxy to understand the ...
Spectra disentangling applied to the Hyades binary Theta^2 Tau AB: new orbit, orbital parallax and component properties
the Hyades binary Theta^2 Tau AB orbital parallax component properties
2011/1/11
Theta^2 Tauri is a detached and single-lined interferometric-spectroscopic binary as well as the most massive binary system of the Hyades cluster. The system revolves in an eccentric orbit with a peri...
Relation between a Function of the Right Ascension and the Angular Distance to the Vertex for Hyades Stars
Moving clusters Hyades cluster open clusters Hyades astrometric and kinematic
2009/5/14
In this paper, relation was developed for Hyades stars between
a function of the right ascensions and the angular distances from the vertex.
The precision criteria of this relation are very satisfac...
