Astronomers have discovered an unusual dead neutron star Swift J1818.0-1607 that may be the “missing link” between magniture and pulsars. It is reported by ScienceAlert.
The space object was detected by the Burst Alert telescope in the Observatory Swift. Initially, scientists believed Swift J1818.0-1607 Magnetar — a star with a very large magnetic field. It was later revealed that it emits pulsed radio emission, which defines it as the pulsar.
It turned out that the source of radiation is the most rapidly rotating pulsar of all discovered and probably the youngest.
Scientists have known four radiomagnetic, but Swift J1818.0-1607 there feature not found in any of them. During the transition from low frequency to high astronomers have discovered a sharp drop in brightness of the radio emission. Other rudimantary have an almost constant brightness across the radio spectrum.
According to astronomers, the discovery could prove that pulsars can evolve into minitary, and also that the collapsing stars have a magnetic field like him.
The researchers emphasize that definitive conclusions require additional study Swift J1818.0-1607.
