Watch out for changing stellar magnetic fields
The 11-year solar activity cycle is a well-known phenomenon, during which the intensity of the Sun’s magnetic field varies and its polarities reverse. Over the past 30 years, astronomers have […]

Intense magnetic fields detected for the first time in the core of red giant stars
The magnetic field plays a central role in the life of a star. It influences its evolution through the internal mixing of chemical elements. However, because stellar matter is opaque, […]

The origin of the Betelgeuse stellar wind revealed by the first 3D images
Except for the lightest elements (H, He and Li), atoms are formed inside the stars, throughout its life, by nuclear reactions. But they need to escape. Among the most efficient […]
