Surprise! A New Study Challenges Betelgeuse’s Spin

Betelgeuse is a red supergiant star that is expected to explode as a supernova in the future. But one of the mysteries about Betelgeuse is its rotation. Is Betelgeuse really spinning as fast as some observations suggested, or is there another explanation for its apparent rotation?

We will explore a new study by Jing-Ze Ma and others that challenges the idea of rapid rotation of Betelgeuse. They propose that the apparent rotation is due to convection and pulsation on its surface.
