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.
Journal ArticleDOI
Differential Rotation and Dynamics of the Solar Interior
Michael Thompson,Juri Toomre,E. Anderson,H. M. Antia,Gabrielle Berthomieu,D. Burtonclay,S. M. Chitre,Joergen Christensen-Dalsgaard,Thierry Corbard,Marc L. DeRosa,Christopher R.

Rhodes,Jesper Schou,Takashi Sekii,Philip B. Stark,P. R. Wilson +25 more
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.
Journal ArticleDOI
Tracking Solar Gravity Modes: The Dynamics of the Solar Core
Rafael A. García,Sylvaine Turck-Chièze,S. J. Jiménez-Reyes,J. Ballot,Pere L. Palle,Antonio Eff-Darwich,Savita Mathur,Janine Provost +7 more
TL;DR: Using data from the Global Oscillation at Low Frequency instrument, a periodic structure is detected in agreement with the period separation predicted by the theory for gravity dipole modes in the Sun.
Journal ArticleDOI
VIRGO: Experiment for helioseismology and solar irradiance monitoring
Claus Fröhlich,J. Romero,Hansjörg Roth,Christoph Wehrli,B. N. Andersen,T. Appourchaux,V. Domingo,Udo Telljohann,Gabrielle Berthomieu,Philippe Delache,Janine Provost,T. Toutain,D.

Willson +24 more
TL;DR: The VIRGO experiment as discussed by the authors measured the characteristics of pressure and internal gravity oscillations by observing irradiance and radiance variations, to quantify their variability over periods of days to the duration of the mission.
Journal ArticleDOI

TL;DR: The CoRoT (Convection Rotation and Planetary Transits) satellite, launched in December 2006, has now measured oscillations and the stellar granulation signature in three main sequence stars that are noticeably hotter than the sun as discussed by the authors.
