Studying sound waves in stars has given scientists a wealth of information about the internal structure and evolution of these celestial bodies. These waves can either travel around the entire circumference of a star or dart right through its core, depending on the size of the star. For instance, in the Sun, a typical wave completes one cycle in just five minutes.
Red giants, which are much larger than the Sun, have lower-frequency waves that can last for weeks to months. These giants are always vibrating due to new waves constantly appearing. By studying stars of different ages, scientists can gain insights into what will happen to our own Sun as it ages.
The study of sound waves in stars provides valuable information about their life cycles and how they change over time. By analyzing these waves, scientists can better understand the internal structure and evolution of stars, which is crucial for understanding our universe as a whole.
