A. by evaluating the different colors of light radiated by the star
Scientists study the composition of stars by analyzing the light they emit. When light passes through a star's atmosphere, it can produce a spectrum that reveals information about the elements present in the star, as well as their temperatures and other physical properties. This method is known as spectroscopy.
