Exploring the space for new objects, experts from the University of Amsterdam (Holland) came across a star that is truly unique. This star produces relativistic plasma jets, although with its incredible power of the magnetic field this should not happen. It is known that jets appear only for stars with a magnetic field much weaker than the specimen in question. This discovery is a good reason to revise modern theoretical models.
The unusual neutron star in question is part of a binary system called Swift J0243.6 + 6124, which is 24 thousand light years away from our planet. The object studied by experts receives the substance from a larger colleague, in the process of which an accretion disk is formed. From the poles of the body emanate jets of ionized particles whose speed is almost equal to the speed of light.
In the entire history of observations, astronomers have fixed jets in various space objects, including black holes, but they never appeared in stars with a powerful magnetic field. And it was a well-founded belief that this component blocks the appearance of jets.
From the Swift J0243.6 + 6124 system, scientists caught radio emission, indicating the presence of jets there, which are a hundred times weaker than the known analogues. At the same time, the neutron star shows an incredible magnetic field strength that surpasses the solar one an unbelievable ten trillion times. Thus, we get a refutation of the theory, according to which, relativistic jets are suppressed by a powerful magnetic field, preventing the accretion disk from moving.
In this riddle, scientists still have to figure out, but one of the versions is already being worked out. So, despite the powerful magnetic field Swift J0243.6 + 6124, the jets still originate, and the large rotational energy of the disk helps in this matter.
