Astronomers of the Xinjiang Astronomical Observatory (China) discovered the PSR J1720-0533 radio radiopulsar related to “black widows” due to the plasma linlication. This is reported in an article published in the Astrophysical Journal Letters magazine.
Observations were carried out using FAST radio telescope. It turned out that the brown dwarf rotates around the radio lights, surrounded by plasma – the ionized gas cloud, which acts as a gravitational lens, reinforcing radio emission. Pulsar is a “black widow”, because gradually “eats” brown dwarf, the total destruction of which will take 10 in the 10th degree. This forecast is based on the calculation of the speed of mass loss equal to 10 per minus of the 12th degree of the mass of the Sun per year.
Researchers found that the radiation of PSR J1720-0533 during the occurrence of the eclipse with brown dwarf shows quasi-periodic modulations that can be caused by plasma linlication. In addition, astronomers discovered that brown dwarf has a fairly strong magnetic field.
