Astronomers have shown that a quick burst FRB 180916.J0158+65 may be a pulsar in a binary system, the orbit of which intersects the asteroid belt. The model helped to explain previously detected fuzzy intervals of this event and the number of flashes of the energy and predict the properties of the belt objects.

Fast radio bursts (FRB — Fast Radio Bursts) are called flares of radio emission lasting a few milliseconds. For the first time about this event became known in February 2007 — then the scientists found a short strong signal in the archival observations. Since then, radio telescopes have registered over hundreds of FRB, some of which were repetitive. The nature of fast radio bursts is still unknown: there are several theoretical models that reliably confirm or refute that has not yet managed (of which our edition told astrophysicist Sergey Popov).
Event FRB 180916.J0158+65 presently considered the closest to the Ground fast burst — its source is located in a spiral galaxy SDSS J015800.28+654253.0 at a distance of 457 million light years from us. At the same FRB scientists first discovered lax the frequency of the signal, it repeats approximately every 16 days with the active phase of about four days. The repetition narrow the scope of possible reasons for FRB, because of the repeated signal cannot be the result of single events (e.g., collisions of stars). Nevertheless, a clear version of the origin of this burst yet.
Chinese researchers Zsiga Let (Z. G. Dai) and Shiqi Zhong (Zhong S. Q.) the School of astronomy and space science, Nanjing University, considered one of the explanations of the behavior of FRB 180916.J0158+65. The authors suggested that the source signal is the binary system of the pulsar (neutron star) and a body of stellar mass that surrounds the asteroid belt. Crossing the latter, the pulsar is confronted with its objects — the result of the gravitational energy is released as radiation.
