Findings

Seismology can detect differences in solar models based on abundances.

The technique addresses opacity inconsistencies caused by abundance revisions.

Potential for improved accuracy in solar composition measurements.

Abstract

The revision of the photospheric abundances proferred by Asplund et al has rendered opacity theory inconsistent with the seismologically determined opacity through the Sun. This highlights the need for a direct seismological measurement of solar abundances. Here we describe the technique used to measure abundances with seismology, examine our ability to detect differences between solar models using this technique, and discuss its application in the Sun.
