Solar oscillations are waves that travel through the Sun's interior, caused by the movement of plasma and magnetic fields. These oscillations can be detected as variations in the Sun's surface brightness and are important for understanding its internal structure and dynamics. These waves can be classified into different modes, such as p-modes and g-modes, depending on how they propagate. Studying solar oscillations helps scientists learn more about the Sun's temperature, density, and rotation, contributing to our knowledge of stellar behavior and the broader field of astrophysics.
