Which stars are metal-poor?

Question

Quizplus · Accepted Answer

Population II stars are typically older and more metal-poor than Population I stars. Metal-poor stars are those with lower abundances of heavier elements such as iron, which were not present in the early universe and were created through nucleosynthesis in stars over time. Open-cluster stars and very young stars are likely to have higher metallicities, as they have formed more recently and therefore have had more time to accumulate heavier elements.
