The Bulge/Halo interface rotational kinematics from [Fe/H] = −3.0 to Solar
Published online by Cambridge University Press: 07 August 2017
Abstract
Kinematics and abundances have been determined for a large sample of K giants in a field at ∼2 kpc from the center to study the relationship between the bulge and the halo. There are two different kinematic groups evident. The metal-poor stars have low rotation and high velocity dispersion, and so can be associated with the halo. The metal-richer stars have intermediate rotation. Our data suggest that the bulge and halo could be separate kinematical entities.
