A neutron star truly has a unique magnetic field properties that it could change how we understand these enigmatic objects. It could also be a representative of an entirely new class of neutron stars.
… never before had a neutron star been detected with a magnetic field from one angle, and without one at others…
GRO J2058+42 is a pulsar neutron star about 30,000 light-years (9 kiloparsecs) away. Its binary companion is a type of star that spins so fast, it is spitting out a disc of material around its equator - a decretion disc. That's not super common, but not rare either.
The neutron star has a spin period of 196 seconds - relatively slow for a pulsar, but not outrageously. It's also what's known as an X-ray transient object, with variable X-ray emission.
