Dr. Jennifer van Saders - Twinkle, twinkle, little star, now I see you as you are: How we see inside a star with sound

We have sought to understand the internal workings of stars for as long as we have done astronomy, with the Sun as our first and best-studied star. Today, the technique of “asteroseismology” has revolutionized our view: just as seismology here on Earth reveals the interior of our own planet, asteroseismology of the stars allows us to view their central engines and structures.
