- n. The study of the propagation of pressure waves in stars
Bill Chaplin, speaking at the AAAS conference in Washington, said that Kepler was an exquisite tool for what is called "astroseismology".
Using a technique called astroseismology they were able to detect the flickers of light caused by these starquakes and reconstruct the sound produced by the star.
Bill Chaplin of the University of Birmingham told the annual meeting of the American Association for the Advancement of Science that astroseismology was, in essence, listening to the "music of the stars".
Such precision light-level measurements also work for astroseismology, because as sound waves resonate within a star, they slightly change both the brightness and the colour of light that is emitted.
PLATO, which is an astroseismology mission being sold as an exoplanet mission.
It has the dual objectives of searching for extrasolar planets and performing astroseismology.
