Skywatch: Good vibrations yield more information about stars

Astronomers using the W.M. Keck Observatory analyzed the vibrations of a star to learn more about its interior, almost as if listening to the star’s music. The study used the Keck Planet Finder, an extremely high- precision instrument, to detect slight oscillations rippling through the star. This new instrument has enabled astronomers to listen to vibrations of stars that were once too quiet to be detected.
