Magnetar
Videos
A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma ray

Neutron star

A neutron star is the gravitationally collapsed core of a massive supergiant star. It results from the supernova explosion of a massive star—combined with gravitational collapse—that compresses the co

…A magnetar is a type of neutron star with an extremely powerful magnetic field (~109 to 1011 T, ~1013 to 1015 G). The magnetic-field decay (or dissipation) powers the emission of high-energy…
