How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

Magnetic fields may speed up dying stars’ rotation
A Kyoto University team has discovered that magnetic field geometry inside massive stars can either slow or accelerate their rotation in the final stages before collapse. Using 3D magnetohydrodynamic ...

Why do stars change their spin as they near the end of their lives? Scientists explain
The interaction between the internal rotation and magnetic fields retards or speeds up the spin rate.
Lower panel shows a collapsing plasma cloud with uniform magnetic field (red).Top Right: Compression alone amplifies the field. Bottom Right: Collapse-driven turbulence accelerates dynamo ...
Why stars spin down, or up, before they die Magnetic fields in the convection zone drives the rotation evolution of massive ...
