Population I stars are a category of stars that are relatively young and metal-rich, meaning they contain a higher proportion of elements heavier than hydrogen and helium. These stars are typically found in the Milky Way galaxy's spiral arms and are often associated with regions of active star formation. These stars include our own Sun and are generally located in open clusters. They are characterized by their bright luminosity and blue-white color, indicating higher temperatures. Population I stars play a crucial role in the chemical evolution of galaxies by producing and dispersing heavier elements into the interstellar medium.
