Stellar seismology is the study of oscillations and vibrations in stars, similar to how seismology studies earthquakes on Earth. By observing these oscillations, scientists can learn about a star's internal structure, composition, and dynamics. This technique helps astronomers understand stellar evolution and the processes that govern a star's life cycle. The primary tool for stellar seismology is the analysis of stellar oscillations, which can be detected through light curves and spectroscopy. These observations provide insights into various stellar properties, such as age, mass, and temperature, contributing to our broader understanding of the universe and the formation of galaxies.
