differential rotation

As stars are not solid bodies, they can also undergo differential rotation.

The differential rotation rate is usually described by the equation:

Differential rotation thus depends on temperature differences in adjacent regions.

For example, the internal sound speed, and the internal differential rotation within the Sun.

Because Neptune is not a solid body, its atmosphere undergoes differential rotation.

The variations in period are thought to be caused by differential rotation at various latitudes, similar to what happens on the surface of our Sun.

In 1690 Cassini noticed that the atmosphere undergoes differential rotation.

Torsional oscillations are the time variation in solar differential rotation.

Together with differential rotation, this causes a large amount of mechanical energy and magnetic flux to pass through the surface.

For observed sunspots, the differential rotation can be calculated as:

The underlying mechanism that causes differential rotation is turbulent convection inside a star.

Differential rotation is caused by convection in stars.

Some later cameras and players attempted to derive the tape position from the differential rotation of the spools with limited success.

Surface differential rotation is observed on stars such as the Sun when the angular velocity varies with latitude.

Polygonal shapes have been replicated in the laboratory through differential rotation of fluids.

Around 1690, Cassini was the first to observe differential rotation within Jupiter's atmosphere.

The experiment then investigates whether the differential rotation profile is stable or not in the presence of an applied magnetic field.

In 1863 he published records of sunspot observations that first demonstrated differential rotation in the Sun.

Solar differential rotation causes shear at the so-called tachocline.

It is also undergoing differential rotation in which the rotation velocity varies by latitude.

Measurements of the time variation in stellar activity can be useful for determining the differential rotation rates of a star.

Solid body rotation assumes that the entire system is moving as a rigid body with no differential rotation.

By doing helioseismological measurements of solar "p-modes" it is possible to deduce the differential rotation.

A machine for the shaping of clay body into flatware by the differential rotation of a profile tool and mould.

There are many ways to measure and calculate differential rotation in stars to see if different latitudes have different angular velocities.
