Magnetars are a rare type of rotating neutron star with some of the most powerful magnetic fields in
Astronomers from the ARC's Center of Excellencethe discovery of gravitational waves is noted that they have never seen anything more strange before. From their observations, they concluded that magnetars have more complex magnetic fields than previously thought. And this casts doubt on the existing science of how neutron stars of this type are born and how they develop over time.
Usually radio pulses have a constant brightness ina wide range of observed frequencies, however, the pulses from J1818 are much brighter at low frequencies than at high frequencies, making it look like a pulsar.
Also in J1818, the magnetic axis is not aligned with the axisrotation, like many other magnetars. The study suggests that this suggests that radio pulses from J1818 are coming from loops of magnetic field lines connecting two closely spaced poles.
This is unlike most ordinary neutron stars, which are thought to have north and south poles on opposite sides of the star.
