Extending the Hyades.


Abstract (from CDS):

We explore the implications of models of the Hyades moving group in which it has a resonant origin, for regions of the Galaxy beyond the solar neighbourhood. We show that while models associated with different resonances can produce nearly identical substructure in the local velocity distribution, the velocity distribution away from the solar neighbourhood has different properties for different models. In particular, there is a variation between different models of where in Galactocentric radius the observed Hyades signal in velocity space is strongest, at a given Galactic azimuth. We note, however, that the uncertainties in currently available data, primarily due to uncertain distances to stars, hide these signatures rather effectively, meaning we are not yet able to determine which resonance is the cause of the Hyades.
