Asteroseismology: Probing Stellar Interiors with Oscillations

Quick fact

Asteroseismology can determine a star's mass, age, and size with astonishing precision — often to a few percent — by analyzing the star's characteristic oscillation frequencies, which depend on the interior physics.

Why this is interesting

When you see a distant star twinkling, it might not just be atmospheric turbulence — it could be the star itself ringing like a bell. How can we learn about the hidden interior of a star just by listening to its vibrations?
