A magnetar is a type of neutron star with an extremely powerful magnetic field (∼10 to 10 T, ∼10 to 10 G). The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. The existence of magnetars was proposed in 1992 by Robert Duncan and … See more Like other neutron stars, magnetars are around 20 kilometres (12 mi) in diameter, and have a mass of about 1.4 solar masses. They are formed by the collapse of a star with a mass 10–25 times that of the See more Unusually bright supernovae are thought to result from the death of very large stars as pair-instability supernovae (or pulsational pair-instability supernovae). However, recent research by astronomers has postulated that energy released from newly formed … See more • McGill Online Magnetar Catalog McGill Online Magnetar Catalog -- Main Table See more As of July 2024 , 24 magnetars are known, with six more candidates awaiting confirmation.

Astronomers have debated the origin of Soft Gamma Repeaters since they were first observed in 1979. With this discovery, however, researchers believe the origin of Soft Gamma Repeaters lies in the 'starquake' phenomena of ...
