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 ...

As the team reports today in the journal Science Advances, the long-period solar oscillations discovered by MPS scientists in 2021 play a crucial role in controlling the Sun’s rotational pattern.

The period of rotation near its equator is 26.5 days, at sun spot zone (16 degrees north) it is 27.3 days, and at the pole it is 31.1 days. The Sun’s enormous core temperature of 15 million ...

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 ...

SINCE the introduction of the Doppler-Fizeau principle one of its most interesting and. important applications has been to the determination of the velocity of the sun's rotation by the ...

Until now, the sun has been the only star for which it has been possible to extract a rotational profile, given the distance of other stars. In their study, however, Tuomi and colleagues were able ...

Except for the youngest stars, the true rotation of those similar to the Sun is unknown, and there are few studies of mature solar twins or of more evolved ones.

"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 certainly does rotate - it has a rotational period of about 25 days. This is apparent if you have ever used a telescope to project images of the sun onto a piece of white card so that you ...

The researchers therefore also studied more than 2500 Sun-like stars with unknown rotation periods. Their brightness fluctuated much less than that of the other group. These results allow two ...

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 ...
