Breaking the previous record by 60 percent.
generate the strongest magnetic fields in the universe. These magnetic fields, close to a neutron star's surface, can only be measured accurately and directly by looking for cyclon resonance scattering features . The Insight-HXMT team discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary Swift J0243.6+6124, which translates to a surface magnetic field of more than 1.6 billion Tesla..
Time and again, the astronomy satellite has illustrated its ability to explore the energy spectrum. And this time, it beat its previous record by 60 percent.X-ray binary system comprises a neutron star and its companion star. The gas of the companion star falls towards the neutron star, forming an accretion disk. In turn, the plasma in the accretion disk will fall along magnetic lines to the neutron star’s surface, releasing powerful X-ray radiation.
This phenomenon can be used to directly measure the strength of the magnetic field near the surface of a neutron star as the energy of the absorption structure corresponds to the strength of the surface magnetic field., objects whose X-ray luminosity far exceeds that of canonical X-ray accreting pulsars, have previously been discovered in several galaxies far from the Milky Way.
Insight-HXMT made detailed and broadband observations of the outburst of Swift J0243.6+6124, the Milky Way's first ultraluminous X-ray pulsar, and unambiguously discovered its cyclotron absorption line. This particular line revealed energy up to 146 keV, which equals a surface magnetic field of more than 1.
