Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar ...

Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their ...

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 ...

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 ...

Many objects in space rotate. Earth completes a spin in roughly 24 hours, while Venus takes a whopping 243 Earth days. The moon's rotational period is about 27 days. The sun, it turns out, also ...

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 ...
