It was this so-called "dipolar radial velocity map" on the outer layer of Betelgeuse that scientists interpreted as rapid rotation.

From afar, Logan Gilbert’s velocity dip was immediately noticeable Wednesday night, if not outright concerning. Up close, though, the radar-gun readings weren’t an issue for the Mariners’ ace.

In fusion experiments, understanding the behavior of the plasma, especially the ion temperature and rotation velocity, is essential. These two parameters play a critical role in the stability and ...
