A team of solar physicists has reported the discovery of global oscillations of the Sun with very long periods, comparable to the 27-day solar rotation period. The oscillations manifest themselves ...

In addition to the 5-minute oscillations, much longer-period oscillations were predicted to exist in stars more than 40 years ago, but had not been identified on the Sun until now.

The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations ...

It's very easy for students to measure the period of oscillation of the pendulum and to change things like string length or amplitude.

Long-period oscillations control the Sun’s differential rotation High-latitude long-period oscillations provide a feedback mechanism that limits the Sun’s pole-to-equator differential rotation.

“The long-period oscillations depend on the Sun’s rotation; they are not acoustic in nature”, says Laurent Gizon, lead author of the new study and director at the MPS. “Detecting the long-period ...

“The long-period oscillations depend on the Sun’s rotation; they are not acoustic in nature”, says Laurent Gizon, lead author of the new study and director at the MPS.

The sun's differential rotation pattern has puzzled scientists for decades: While the poles rotate with a period of approximately 34 days, mid-latitudes rotate faster and the equatorial region ...
