Stellar associations are groups of young stars that are loosely bound together by gravity and formed from the same molecular cloud. These stars are typically located within the same region of space and are thought to have formed around the same time, resulting in a similar age range and composition. Stellar associations are important for studying the formation and evolution of stars, as well as the dynamics of star clusters and their interactions with the surrounding interstellar medium. Researchers study stellar associations to gain insights into the processes that drive star formation and the development of planetary systems.
