On the origin of the Hercules group: II. the Trojan quasi-periodic identity on the orbital level
Yusen Li, Kenneth Freeman, Helmut Jerjen
The Hercules kinematic group is a stellar anomaly structure observed in the solar neighbourhood (SNd). In the previous paper, we analysed chemical signatures and related the origin…

On the origin of the Hercules group: I. chemical signatures indicating the outer bar origin
Yusen Li, Kenneth Freeman, Helmut Jerjen +3
The Hercules kinematic group is a kinematic anomaly of stars observed in the solar neighbourhood (SNd). In this series of papers, we present a comprehensive study of this structure…
