Stellar discovery by Queen's researcher
Ph.D. candidate Matt Shultz has discovered the first massive binary star, epsilon Lupi, in which both stars have magnetic fields. A binary star is a star system consisting of two or more stars, orbiting around their common center of mass. (2015-09-11)

Not everything is ferromagnetic in high magnetic fields
High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in zero field. Usually, high fields exceeding a certain critical value force the moments to align in the same direction as the field leading to ferromagnetic arrangement. However, a recent study showed that this is not always the case. The experiments took place at the high-field magnet at HZB's neutron source BER II. (2020-02-10)

Scale-invariant resistivity in cuprates
A new intriguing property of cuprate superconductors has been identified, says a new study, which shows that in very high magnetic fields, the resistivity of a thin-film lanthanum-based cuprate scales linearly with the field. (2018-08-02)

NASA's SDO observes fast-growing sun spot
Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours. It has grown to over six Earth diameters across but its full extent is hard to judge since the spot lies on a sphere not a flat disk. (2013-02-20)

High field magnet at BER II: Insight into a hidden order
A specific uranium compound has puzzled researchers for thirty years. Although the crystal structure is simple, no one understands exactly what is happening once it is cooled below a certain temperature. Apparently, a 'hidden order' emerges, whose nature is completely unknown.Now physicists have characterised this hidden order state more precisely and studied it on a microscopic scale. To accomplish this, they utilised the High-Field Magnet at the HZB that permits neutron experiments to be conducted under conditions of extremely high magnetic fields. (2017-10-20)

The solar wind breaks through the Earth's magnetic field
Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth's magnetic field. Researchers at the Swedish Institute of Space Physics in Uppsala now have an answer to one of the questions about how this actually occurs. (2014-06-11)

(2016-02-03)

NASA's SDO shows a little rain on the sun
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection, and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all three. (2013-02-20)

Strong magnetic fields discovered in majority of stars
An international group of astronomers led by the University of Sydney has discovered strong magnetic fields are common in stars, not rare as previously thought, which will dramatically impact our understanding of how stars evolve and potentially lead to a better understanding of the sun's 22-year magnetic cycle -- known to affect communication systems and cloud cover on Earth. (2016-01-04)

Magnetic fields created before the first stars
Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has been researched by Prof. Dr. Reinhard Schlickeiser at the Institute of Theoretical Physics of the Ruhr-Universität Bochum. In the journal Physical Review Letters, he describes a new mechanism for the magnetization of the universe even before the emergence of the first stars. (2013-01-02)

Yes, the sun is an ordinary, solar-type star after all

As stars form, magnetic fields influence regions big and small
Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn't the only force at work. Both turbulence and magnetic fields battle gravity, either by stirring things up or by channeling and restricting gas flows, respectively. New research focusing on magnetic fields shows that they influence star formation on a variety of scales, from hundreds of light-years down to a fraction of a light-year. (2015-03-30)

Magnetic fields play larger role in star formation than previously thought
The simple picture of star formation calls for giant clouds of gas and dust to collapse inward due to gravity, growing denser and hotter until igniting nuclear fusion. In reality, forces other than gravity also influence the birth of stars. New research shows that cosmic magnetic fields play a more important role in star formation than previously thought. (2009-09-09)

Researchers propose technique for measuring weak or nonexistent magnetic fields

This can help to limit exposure in electric and hybrid vehicle architectures, and in domestic and work environments. (2018-07-11)
