Chemokinematics of the V/EMP stars from this work. (Panel a) Energy E vs angular momentum in ɀ direction Lɀ. The substructure regions from Naidu et al. (2020) identified using RGB stars in the H3 survey are shown as coloured ellipses to associate V/EMP stars from this work. (Panel b) Same as top centre, but without the substructure ellipses. Stars with energy greater than 0 are high-energy and/or unbound stars in the Milky Way potential used. (Panel d) Rotational component of the action Jϕ vs vertical action Jɀ . (Panel f) Rotational action Jϕ vs eccentricity. (Panel c) The INT sample is divided into three dynamical groups according to their apocentre and Zmax . The grey shaded area denotes the forbidden region in which Zmax > apocentre. The vertical and horizontal lines separate the groups. (Panel e) Groups are shown in apocentre vs pericentre view. The grey shaded area denotes the forbidden region in which pericentre > apocentre. (Panel g) Groups in apocentre vs eccentricity view. All EMP stars observable by the spectroscopic follow-up program are shown in grey.
