Description
Global Oscillation Network Group data reveal that the internal structure
of the sun can be well represented by a calibrated standard model.
However, immediately beneath the convection zone and at the edge of the
energy-generating core, the sound-speed variation is somewhat smoother
in the sun than it is in the model. This could be a consequence of
chemical inhomogeneity that is too severe in the model, perhaps owing to
inaccurate modeling of gravitational settling or to neglected
macroscopic motion that may be present in the sun. Accurate knowledge of
the sun's structure enables inferences to be made about the physics that
controls the sun; for example, through the opacity, the equation of
state, or wave motion. Those inferences can then be used elsewhere in
astrophysics.
