Our grasp of how stars rotate is "insufficient," with implications on our ability to understand the causes of phenomena on the sun like solar flares and coronal mass ejections that cause aurora and ...

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 ...

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 ...

Analysis of a century of solar images from an Indian observatory reveals that different features on the Sun’s chromosphere 1, the layer above the visible photosphere, all show the star’s uneven ...

Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers at NYU Abu Dhabi that challenges current science on how stars rotate. Until ...

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 ...
