Observational Results of Full-Disc Helioseismology

Abstract

AbstractEver since the discovery of the low-degree p modes was announced by Claverie et al. (1979), full-disc helioseismology – seismology of the Sun based on the study of sunlight integrated across the entire disc – has contributed very significantly to our understanding of the deep solar interior and the origin and nature of the oscillation modes which probe it. This paper touches on the principal observational techniques used for full-disc helioseismology and outlines key results and their implications.
