Rotating convection and the solar differential rotation

open access: yesSolar Physics, 1994
We discuss the implication of a numerical experiment on rotating convection and its relevance to the construction of a model for the solar differential rotation.

The solar differential rotation: Present status of observations

Solar Physics, 1985
The present status of observations regarding the solar differential rotation is reviewed from contributions published in the last two decades. The paper does not deal with the theory; it mentions theoretical aspects only where they are needed to guide and to understand observational efforts and results.

On the differential rotation of the solar photosphere

Solar Physics, 1994
It is shown that sunspots as tracers can give the same results for the differential rotation of the solar photosphere as the Doppler-shift measurements, if the sunspots used have only insignificant motion relative to their immediate photospheric surroundings.

Rigid and differential rotation of the solar corona

Solar Physics, 1974
The rotation of the solar corona has been studied using recurrence properties of the green coronal line (5303 A) for the interval 1947–1970. Short-lived coronal activity is found to show the same differential rotation as short-lived photospheric magnetic field features. Long-lived recurrences show rigid rotation in the latitude interval ±57°.5.

Solar Differential Rotation and Oblateness

Science, 1969
An investigation of the time development of differential rotation produced by the solar wind torque indicates that the sun has a rapidly rotating core.

Differential rotation of short-lived solar filaments [PDF]

open access: yesSolar Physics, 1977
We have measured the rotation rate of short-lived solar filaments as a function of their latitude. The resulting rotation curve appears to be somewhat flatter than the corresponding curve for long-lived ...

Differential Rotation and the Solar Oblateness

Nature, 1967
A few weeks ago, Dr I. W. Roxburgh questioned an earlier argument by Professor R. H. Dicke that the observed flattening of the Sun would account for part of the rotation of the orbit of Mercury otherwise attributable to general relativity. Roxburgh advanced arguments which suggest that the surface of the Sun may not be an equipotential surface, largely

The Differential Solar Rotation

1994
Theory and observations of the solar differential rotation are reviewed, concentrating on recent developments. Reynolds stresses produced by stratified rotating turbulence have recently become available as fully nonlinear functions of the angular velocity. A model based on this theory has reproduced the solar rotation; almost no tuning of the theory to

Differential solar rotation depends on solar activity

Nature, 1979
SUNSPOTS have long been used as tracers to determine the rotation rate of the Sun. Scheiner1 noted 250 years ago that low-latitude sunspots rotate more rapidly than those at high latitude (‘differential rotation’). In a recent review, Howard2 stressed the limitations of the sunspot technique for determining rotation rate and differential rotation, as ...
