Solar rotation - Wikipedia, the free encyclopedia
Solar rotation is able to vary with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator (latitude φ=0 deg), and to decrease as lati...

This lesson has students use Solar and Heliospheric Observatory (SOHO) data from the EIT (Extreme-ultraviolet Imaging Telescope) instrument on the spacecraft to discover differential rotation of the Sun. They will realize that the Sun has a north and south pole, just as the Earth does, and rotates on its axis.

Earth has a radius of about 6,400 km, the sun has a radius of about 7.0 x 105 km, and a rubber ball has a radius of 6.4 cm. If you were to construct a scale model of the solar system using the rubber ball to represent Earth, ... Precession of the rotation axis of Earth is caused by ... Differential rotation of the sun...

Title:; Wavelet analysis of stellar differential rotation. II. The Sun in ultraviolet ... Among the several methods to study differential rotation on stellar surfaces the observation of a stellar butterfly diagram, i.e. monitoring the rotation period over a complete activity cycle, is the only method which can be applied...

Title : CONVECTION AND THE DIFFERENTIAL ROTATION OF THE SUN, ... It appears that, although the effect of rotation is negligible in the photosphere, it may double the superadiabatic gradient in the deep convective zone. Consequently, if convective heat transport is the same at the poles as at the equator of the Sun,

Turbulent Convection and Differential Rotation in the Sun ... Differential rotation and cycles of magnetic activity are intimately linked dynamical processes within the deep shell of highly turbulent convection occupying the outer 30 percent of the Sun just below its surface.
