Stellar population refers to the composition and characteristics of a group of stars within a specific region of space. This area of research focuses on analyzing the distribution, age, size, mass, luminosity, and metallicity of stars within a particular region to better understand their formation, evolution, and overall behavior. By studying stellar populations, astronomers can unravel the history and dynamics of galaxies, as well as gain insights into the underlying physical processes that govern the life cycles of stars. Additionally, stellar population studies provide valuable information about the Universe's age, structure, and evolution.
