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 ...

The strength and geometry of the magnetic field, combined with the properties of convection in the oxygen region can cause ...

Scientists thought they knew what happened to stars in their dotage, but thanks to new supercomputer simulations, we now ...

Research BackgroundWhen walking through a dense forest, a compass is indispensable for knowing which direction to take, and it works because the Earth ...

At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge ...

Scientists in Japan have confirmed through advanced simulations that an Earth-like dipole magnetic field can stably exist in two opposite polarities with equal likelihood. This discovery offers a ...

From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down ...
