Star with different internal driving force than the sun
Copenhagen, Denmark (SPX) May 09, 2016
A star like the Sun has an internal driving in the form of a magnetic field that can be seen on the surface as sunspots. Now astrophysicists from the Niels Bohr Institute have observed a distant star in the constellation Andromeda with a different positioning of sunspots and this indicates a magnetic field that is driven by completely different internal dynamics. The results are published in the scientific journal, Nature. Stars are glowing balls of gas that through atomic processes release energy ... read more
