A neutron star with an extremely strong magnetic field.
- ‘Astronomers have found evidence suggesting that a rare group of ultradense stars are magnetars - the objects with the strongest magnetic fields known in the universe.’
- ‘Schwartz and colleagues provide the first observational evidence that the giant flare was produced when the crust of the magnetar could no longer plastically compensate the internal magnetic stress and finally cracked.’
- ‘I know a place where the magnetic fields would rip you apart, atom by atom: the surface of a neutron star, a magnetar.’
- ‘Thought to be a mighty cataclysm in a super-dense, highly magnetized star called a magnetar, it emitted as much energy in two-tenths of a second as the sun gives off in 250,000 years.’
- ‘The new infrared echo indicates the Cassiopeia A neutron star is active and suggests it may be an exotic, spastic type of object called a magnetar.’
1990s: from magnetic + -ar as in pulsar and quasar.
