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: ...

For example, we know at which rotational rates the dynamo effect occurs and which magnetic field structures we can expect," says Giesecke. The scientific community involved with dynamos is eagerly ...

Forbes contributors publish independent expert analyses and insights. I cover aerospace, astronomy & hosted The Cosmic Controversy Podcast. May 27, 2017, 10:50pm EDT May 28, 2017, 02:42am EDT This ...

Magnetars are neutron stars endowed with the strongest magnetic fields observed in the universe, but their origin remains controversial. In a study published in Science Advances, a team of scientists ...

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 ...

The differential rotation between the Moon's core and mantle may have powered the ancient lunar dynamo, either continuously over several hundred million years or intermittently after large impacts.

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 ...

The magnetic field of the Sun is generated by a dynamo effect caused by its convective and rotational movements. It will evolve when our star becomes a red giant in the distant future. Visual ...

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 neutron star is the extremely compressed leftover core of a star that began life with between 10 and 30 times the Sun’s mass. Moving charges do generate magnetic fields, as you suggest; however, the ...

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 ...
