How low-mass stars produce their ubiquitous magnetic fields has long puzzled astronomers. Models of how Earth accomplishes this task could hold the key to understanding the phenomenon on such stars.

Different stars can exhibit different levels of activity. The Sun's signs of solar activity are rather feeble on an astronomical scale. Other stars are up to ten times more active. While researchers ...

In their interiors, stars are structured in a layered, onion-like fashion. In those with solar-like temperatures, the core is followed by the radiation zone. There, the heat from within is led ...

Image of the Sun taken from the Solar Dynamics Observatory satellite, showing the quiet corona and magnetic structures like coronal loops, which trace the intricate patterns of magnetic field lines ...

Magnetars are neutron stars characterized by some of the most powerful magnetic fields in the Universe, as well as their intense X-ray and gamma-ray emissions and outbursts. An international team of ...
