How Starquakes in Red Giants Reveal Their Internal Structure

Quick fact

By analyzing the g-mode oscillations of red giants, astronomers have discovered that the cores of some red giants rotate up to ten times faster than their surfaces—a result impossible to obtain without starquakes.

Why this is interesting

All stars shimmer, but the trick is to listen to the subtle 'music' of their surface to know what's going on deep inside the giant, glowing star. What hidden truths about a red giant's heart are encoded in its starquakes?
