Magnetar

A magnetar is a neutron star with an extremely powerful magnetic field (about 100 to 1000 times stronger than the Crab Nebula pulsar), the decay of which powers the emission of copious amounts of high-energy electromagnetic radiation, particularly X-rays and gamma-rays. The theory regarding these objects was formulated by Robert Duncan and Christopher Thompson inSeguir leyendo
