Web8 sep. 2024 · Helioseismology – the study of internal oscillations of the Sun, based on surface vibrations – can be used to detect sunspots on the far side of our home star. That's because accumulations of magnetic fields, such as sunspots, can affect the speed of sound waves bouncing around inside the Sun. WebHelioseismology has allowed us to study the structure of the Sun in unprecedented detail. One of the triumphs of the theory of stellar evolution was that helioseismic studies had …
