Full definition of astroseismology

Noun

1. (star) The study of the propagation of pressure waves in stars
• The study of the sounds within stars is known as astroseismology, and a separate report in Science details the findings of more than 500 stars whose deep rumblings Kepler has measured.
  As convection processes within stars move masses of material up from the core, great pressure waves - in essence, sound waves of very low frequency - are created.
