The Sun’s Interior Structure and Dynamics, and the Solar Cycle

  • Chapter
The Solar Activity Cycle

Part of the book series: Space Sciences Series of ISSI ((SSSI,volume 53))

Abstract

The Sun’s internal structure and dynamics can be studied with helioseismology, which uses the Sun’s natural acoustic oscillations to build up a profile of the solar interior. We discuss how solar acoustic oscillations are affected by the Sun’s magnetic field. Careful observations of these effects can be inverted to determine the variations in the structure and dynamics of the Sun’s interior as the solar cycle progresses. Observed variations in the structure and dynamics can then be used to inform models of the solar dynamo, which are crucial to our understanding of how the Sun’s magnetic field is generated and maintained.
