Every star, including the Sun, hosts a magnetic field. One of the most notable products of stellar magnetic activity is X-ray emission (Fig. 1), most of which comes from active regions — areas on a ...

We report on our continued efforts to understand and delineate the magnetic dynamo-induced behavior/variability of red dwarf (K5 V – M6 V) stars over their long lifetimes. These properties include: ...

Flows of molten metal can generate magnetic fields. This so-called dynamo effect creates cosmic magnetic fields, like those found on planets, moons and even asteroids. Over the coming years, a ...

The solar dynamo is a research area focused on understanding the physical mechanisms by which the Sun’s internal plasma motions generate and sustain its large-scale magnetic field. It integrates ...

A German scientist believes he has resolved a three-decade mystery about why Mercury, the closest planet to the Sun, has such a weak magnetic field. Mercury is believed to generate its magnetism in ...
