The presence and structure of these clouds tells us that Jupiter exhibits a differential rotation-not all parts of the planet's gaseous envelope move at the same rate.
22.
Sunspots, regions of intense magnetic disturbances, are also known to move more rapidly in the sun's midsection than at higher latitudes, a result of an unexplained differential rotation.
23.
Photometry has also shown that the surface of Epsilon Eridani, like the Sun, is undergoing differential rotation, which means that the rotation period at the surface varies by latitude.
24.
For gaseous / fluid bodies, such as stars and gas giants, the period of rotation varies from the equator to the poles due to a phenomenon called differential rotation.
25.
If the fluid is in a state of differential rotation about a fixed origin, this Lorentz force can be surprisingly disruptive, even if the magnetic field is very weak.
26.
In both of these cases thermal convection is likely to be the primary energy source, though in the case of the Sun differential rotation may also play an important role.
27.
"' Richard Christopher Carrington "'( 26 May 1826 27 November 1875 ) was an English aurorae; and whose 1863 records of sunspot observations revealed the differential rotation of the Sun.
28.
For one thing, the seismic data can tell you about the differential rotation of liquid metal in the earth's core _ a key factor causing variations in the earth's magnetic field ."
29.
This causes mixing of helium to the surface, a process that is enhanced by rotation, possibly by differential rotation where the core is spun up to a faster rotation than the surface.
30.
Similarly, the differential rotation of stars is thought to be what gives rise to magnetically-driven phenomena such as sunspots and solar flares .-- talk ) 20 : 46, 14 August 2015 ( UTC)
