Illustration depicting asteroseismology - the study of oscillations inside stars. Because a star's different oscillation modes are sensitive to different parts of the star, they inform astronomers about the internal structure of the star, which is otherwise not directly possible from overall properties like brightness and surface temperature. The interior of a Sun-like star is shown, with some oscillation modes superimposed, along with some sound wave trajectories.
