Solar rotation, a fundamental characteristic of the sun, is second in importance only to the Schwabe cycle, an approximately 11-year cycle. The energy and matter of the solar atmosphere originate from ...

In the early 2000s, a new set of data revised the chemical abundances at the surface of the sun, contradicting the values predicted by the standard models used by astrophysicists. Often challenged, ...

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 ...

The sun : a slowly rotating star / J.-P. Zahn -- What is coming : issues raised from observation of the shape of the sun / J.-P. Rozelot -- Effects of rotation on stellar p-mode frequencies / M. J.

Strong magnetic fields keep the equator spinning faster than the poles and prevent a rotation flip, even as stars slow down with age Researchers at Nagoya University in Japan have conducted the most ...
