Red giants, much larger than the Sun, have lower-frequency waves that can last for weeks to months. On the other hand, smaller stars have higher-frequency waves that ripple around their entire circumference. For instance, in the Sun, a typical wave completes one cycle in just five minutes. These waves are constantly forming and create a continuous vibration in the star.
By studying stars of different ages, scientists can gather information about what will happen to our own Sun as it ages. This research provides valuable insights into the life cycle of stars and helps astronomers better understand the evolution of celestial bodies. In addition to this, researchers also study how sound waves travel in a star’s interior and how long it takes for them to complete one cycle in bigger stars compared to smaller ones.
