The frequency difference between prograde and retrograde sectoral solar oscillations is analysed to determine the rotation rate of the solar interior, assuming no latitudinal dependence. Much of the solar interior rotates slightly less rapidly than the surface, while the innermost part apparently rotates more rapidly. The resulting solar gravitational quadrupole moment is J2 = (1.7±0.4) × 10−7 and provides a negligible contribution to current planetary tests of Einstein's theory of general… Expand
Internal Solar Rotation
The helioseismic determination of the angular velocity distribution within the sun is discussed. In particular, the bulk of the radiative interior of the sun is rotating at more-or-less the same rateExpand
Differential Rotation and Dynamics of the Solar Interior
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. Expand
Magnetic torques and differential rotation
The rotation profile deduced from the measured splitting of solar oscillations raises several problems. The slight decrease in angular velocity within the convective zone can be explained and theExpand

Internal Rotation of the Sun as a Consequence of Instabilities in the Radiative Interior
We consider the effect of the molecular weight gradient in the Sun’s radiative interior on the GSF instability, and deduce the marginal gradient of angular velocity which can be tolerated. The sameExpand
The solar interior - radial structure, rotation, solar activity cycle

The Internal Rotation of the Sun: Implications on the History of Its Angular Momentum
Recent helioseismological data have revealed that the internal rotation of the Sun may not differ very much from that observed on its surface. This implies that the angular momentum loss must beExpand

Internal rotation of the Sun
The low surface rotation rate of the Sun and other main-sequence stars is believed to be the result of angular momentum loss due to a stellar wind1. This loss also leads to a differential rotation,Expand
