Twenty years later, the secret of an unusual neutron star has been revealed. All thanks to volunteers

The team identified the neutron star from its regularly pulsing gamma rays, but the object was perfectly

invisible in radio waves.

To unambiguously prove the existenceneutron star, it is necessary to detect not only its radio waves or gamma rays, but also their characteristic pulsations. The spin of the neutron star causes this regular blinking, similar to the blinking of a distant beacon. In this case, a neutron star is called either a radio or a gamma pulsar.

The neutron star rotates around its axis withat over 30,000 rpm, making it one of the fastest spinning machines. At the same time, its magnetic field, which is usually extremely strong in neutron stars, turned out to be extremely weak here.

In order to discover the object, 10 thousand volunteers donated to a supercomputer [email protected] the power of their computer cards. In less than two weeks, the team made a discovery that would have taken centuries on a conventional computer.

After identifying the gamma pulsar, the commandtried to find his radio waves. They found no trace, although they used the largest and most sensitive radio telescopes in the world, including the Lovell Jodrell Bank Telescope. This means that the neutron star, or PSR J1653-0158, has become the second rapidly rotating pulsar from which no radio waves are visible. There are two possible explanations: either the pulsar does not send radio waves to Earth, or, more likely, the plasma cloud envelopes the binary star system so completely that no radio waves reach Earth.
