Population I stars

Population I stars are young stars rich in heavier elements like carbon, oxygen, and metals, formed from gas enriched by previous generations of stars. They tend to be found in the spiral arms of galaxies and often have higher masses and temperatures, making them brighter and bluer. The Sun is an example of a Population I star. Their composition and location differentiate them from older stars, known as Population II, which are metal-poor and located primarily in the galaxy's core or halo. Population I stars play a key role in ongoing star formation and the evolution of galaxies.
