【 摘 要 】

At first glance, the paper’s title, ‘The chemical composition of five stars which show some characteristics of population-II’, is uncharacteristic and ordinary. Diving deeper into different sections of the paper reveals a well-thought experiment, critical analysis, and farsighted conclusions that remain most relevant to date. The authors probably found the five stars intriguing because they are peculiar among the solar neighborhood. They combined all aspects of available observations to understand the nature of these stars in the context of the Galaxy formation. They found a gradient in their chemi-cal and kinematical properties and suggested this could be a result of the chemodynamical evolution of the Galaxy itself, which was a revelation in the 1950s.
