Asteroseismology is the study of the internal structure and dynamics of stars using the analysis of their natural oscillations, or seismic waves. By studying the frequencies and patterns of these oscillations, researchers can learn valuable information about the composition, age, and evolution of stars. This field has provided insights into stellar evolution, the nature of stellar interiors, and the characteristics of exoplanets. It has also facilitated the discovery of new types of stars and opened up new avenues for studying the Universe.
