"Matching the nonlinear simulations to the observations allowed us to understand the physics of the long-period oscillations and their role in controlling the sun's differential rotation," says MPS ...

A team of solar physicists led by Laurent Gizon of the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen in Germany has reported the discovery of global oscillations ...

Oscillators are one of the key elements in various applications as a signal source to generate periodic oscillations. Among them, an optical parametric oscillator (OPO) is a driven harmonic oscillator ...

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 ...

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 at ...

These motions were measured by analyzing 10 years of observations from NASA's Solar Dynamics Observatory (SDO). Using computer models, the scientists have shown that the newly discovered oscillations ...

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 ...

These motions were measured by analyzing 10 years of observations from NASA’s Solar Dynamics Observatory (SDO). Using computer models, the scientists have shown that the newly discovered oscillations ...
