TL;DR: Data from the GONG project and other helioseismic experiments reveal subtle errors in the models, such as an excess in sound speed just beneath the convection zone, which is plausible that the sound-speed differences reflect weak mixing in stellar interiors.

Title,Michael Thompson,Juri Toomre +24 more
TL;DR: In this article, the authors report on joint helioseismic analyses of solar rotation in the convection zone and in the outer part of the radiative core using the Michelson Doppler Imager (MDI) on the Solar and Heliospheric Observatory (SOHO) spacecraft.
Journal ArticleDOI
The Internal Rotation of the Sun
TL;DR: In this paper, a detailed observational picture has been built up of the internal rotation of our nearest star, showing that the radiative interior is found to rotate roughly uniformly, unlike the predictions of stellar evolution models, which had been that the rotation rate would depend primarily on the distance from the rotation axis.
Journal ArticleDOI
Dynamic variations at the base of the solar convection zone
R. Howe,Jørgen Christensen-Dalsgaard,Frank Hill,Rudolf Komm,R. M. Larsen,Jesper Schou,Michael Thompson,Juri Toomre +7 more
TL;DR: Changes in the rotation of the sun near the base of its convective envelope are detected, including a prominent variation with a period of 1.3 years at low latitudes, which may generate the 22-year cycles of magnetic activity.

TL;DR: Frequency splittings derived from GONG observations confirm that the variation of rotation rate with latitude seen at the surface carries through much of the convection zone, at the base of which is an adjustment layer leading to latitudinally independent rotation at greater depths.
