Astroseismology 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 age. This field has gained importance with the advent of space telescopes like Kepler and TESS, which can detect tiny changes in a star's brightness caused by these vibrations. The data collected from Astroseismology helps astronomers understand stellar evolution and the life cycles of stars. It provides insights into phenomena such as supernovae and the formation of neutron stars, enhancing our knowledge of the universe's dynamics.
