INTERNAL-CYCLE VARIATION OF SOLAR DIFFERENTIAL ROTATION [PDF]
The Astrophysical Journal Supplement Series, 2013 The latitudinal distributions of the yearly mean rotation rates measured respectively by Suzuki in 1998 and 2012 and Pulkkinen $\&$ Tuominen in 1998 are utilized to investigate internal-cycle variation of solar differential rotation. The rotation rate at the solar Equator seems to decrease since cycle 10 onwards.

Impact of anti-solar differential rotation in mean-field solar-type dynamos
, 2022 Context. Over the course of their lifetimes, the rotation of solar-type stars goes through different phases. Once they reach the zero-age main sequence, their global rotation rate decreases during the main sequence until at least the solar age ...

Differential Rotation and Dynamics of the Solar Interior [PDF]
Science, 1996 Splitting of the sun's global oscillation frequencies by large-scale flows can be used to investigate how rotation varies with radius and latitude within the solar interior. The nearly uninterrupted observations by the Global Oscillation Network Group (GONG) yield oscillation power spectra with high duty cycles and high signal-to-noise ratios ...

Rotating Turbulent Thermal Convection and Solar Differential Rotation
, 2022 The expansion of the rotating fluid will change the vorticity and rotational speed of the expanding region. In turbulent thermal convection, this microscopic effect is preserved. Tracking the fluid micelles shows that the average vorticity varies with density, producing vorticity transport and angular momentum transport from the low-density area to the

Solar Oblateness and Differentially Rotating Polytropes [PDF]
International Astronomical Union Colloquium, 1970 Dicke and Goldenberg (1967a) measured the solar oblateness to be σ= (5±0.7) × 10-5 and subsequently interpreted this measurement as evidence that the solar interior rotates with a period of 1.d8. With this interpretation, they then showed that the observed oblateness causes an 8% discrepancy in the Einstein prediction of the perihelion advance of ...

Differential Rotation in the Solar Interior [PDF]
International Astronomical Union Colloquium, 1970 One of the big problems in stellar rotation which has been the object of much debate recently concerns the magnitude of the angular velocity in the central regions of the sun. It is a good example of our general ignorance of the distribution of angular momentum in the interiors of stars. There is good reason, of course, for this ignorance.

Probing the rotation rate of solar active regions: the comparison of methods
Open Astronomy, 2022 Sunspot groups are often used as tracers to probe the differential rotation of the Sun. However, the results on the rotation rate variation obtained by different authors are not always in agreement. The reason for this might be a number of effects.

, 2015 VK: Karhunen, J.; ReSoLVEContext. Late-type stars rotate differentially owing to anisotropic turbulence in their outer convection zones. The rotation is called solar-like (SL) when the equator rotates fastest and anti-solar (AS) otherwise.
