Stellar Abundance and Composition

Stellar abundance refers to the different elements found in stars, which are primarily made of hydrogen and helium. Over time, stars fuse these elements into heavier ones, like carbon and oxygen. The composition of a star affects its life cycle, color, and brightness. Astronomers analyze light from stars to identify their chemical makeup and abundance of elements, helping us understand the universe's history, the formation of galaxies, and the creation of planets. Essentially, the elements in stars reveal crucial information about our cosmic environment and the origins of everything we see around us.
