Known magnetars
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 … 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.
