On October 7th researchers from japan’s Institute of Science and Chemistry observed a new magnet called Swift J1818.0-1607, which challenges our traditional understanding of magnets and pulsar. A magnet is a subtype of a pulsar, an extremely dense object consisting mainly of neutres. Magnets and some pulsars emit powerful X-rays, but scientists say they are not produced in the same way: they are thought to be driven by a very strong magnetic field, while some pulsars are driven by the rapid rotation of stars.
For the study, the researchers found that the star had a pulse cycle of 1.36 seconds, the shortest ever observed. Further studies show that it exhibits a spin-down characteristic, which means that it is driven to some extent by rotation, and that it has a magnetic field of 2.7×1014 Gauss, indicating that it is a young magnetic star.
The object has both magnetic and rotating power pulsar features, and researchers believe the discovery could reveal a missing link between the two pulsar.
