The team studying powerful X-ray signals coming from the neutron star GRO J1008-57, calculated that its magnetic field is “tens of millions of times stronger than any ever created in a lab here on Earth.”
Neutron stars have the strongest magnetic fields in the universe.
They found that the magnetic field that corresponded to this neutron star would be about 1 billion Tesla, tens of millions of times stronger than what can be generated in any laboratory on Earth.
The work was created by scientists from the Institute of High Energy Physics under the Chinese Academy of Sciences and the Eberhard Karls University of Tübingen in Germany.
A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich. Neutron stars are the smallest and densest stellar objects, excluding black holes and hypothetical white holes, quark stars, and strange stars. Neutron stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.
