- ~ 10 million different vibrations are excited simultaneously in the solar interior.
- These vibrations combine to produce standing waves through constructive and destructive interference.
- These solar oscillations are thought to be produced due to convection and turbulence in the convective layer of the solar interior.
- Information is extracted from solar oscillations by measuring them with incredible precision and comparing them to simplified theoretical models of the sun.
- This technique is called helioseismology analogous to seismological observations of the Earth's interior structure.
- New ideas about the sun from helioseismology
