Definitions for "Helioseismology"
The study of the Sun's interior by measuring oscillations (ripples) as they appear at the surface. The oscillations are caused by sound waves that originate at different depths inside the Sun. By measuring their travel times and the distance they travel, scientists can study conditions in the Sun's interior.
the study of wave oscillations on the Sun's surface.
Refers to the science of using waves to learn about the Sun. Helios is Greek for ‘sun' or ‘light'; seismos means ‘tremor'; and logos means ‘reasoning' or ‘discourse'. Just as seismologists learn about the interior of the Earth by listening and watching earthquakes, helioseismologists study waves from the Sun, although there are millions of times more waves to observe and listen to.
