Strange phenomena first discovered in 2007, lasting a thousandth of a second, perhaps not from those places attributed to them by the astronomical community. “We presume, that fast radio flashes are not as exotic as they were thought at first, ” – said Avi Loeb (Avi Loeb) from the Harvard-Smithsonian Center astrophysicists (USA).

Double stars as a source of fast radio bursts have not been previously were considered. (NASA illustration.) So far, we have been Only six fast radio bursts are known. And since we are not aware of any signs of approaching such events, all six are found in archival data. All of them were discovered only. once from each point, so further observations of these sources, to put it mildly, are difficult. This, of course, does not mean that events are rare: we just recently started carefully keep an eye on the sky. A detailed analysis of these radio bursts showed following: in order to obtain an observable character, on its way to Such radio waves must pass through a large “column” to the earth electrons. If these electrons were scattered in the intergalactic space, then radio bursts came to us from distances in billions of light years. If we can register something with such gigantic distances – that means the source of the bursts was extremely energetic. Gamma-ray bursts (also relatively fast flashes of huge energies) do not provide the necessary radio frequencies, so that astronomers turned to such exotic events as collapse a neutron star into a black hole, which is possible if as absorption of surrounding matter, the neutron star “overshot” and its the mass exceeded a certain limit, causing a collapse into black hole. Mr. Loeb, as if compensating for the extreme exotic of his other recent work, suggested that everything was much simpler and without involving major players such as neutron stars and blacks holes. In fact, what if radio bursts are generated less energetic events that happened at shorter distances from Of the earth? More precisely – events within our Galaxy that did not occur more than a hundred thousand light-years from the sun. In this case, they will give the desired intensity, even if their source is something more mundane – say, flashing stars. Having done corresponding calculations, astronomers concluded that the electrons in the stellar corona, being grouped into dense streams, can give the same effect as more scattered electrons intergalactic space, presenting them with fast radio bursts mysterious parameters. But even inside our galaxy fast radio bursts must be generated by some very energetic star flares. Today, astronomers know two types of candidates, responsible for such events are low-mass stars, part populations of red dwarfs, and stars with masses close to the Sun, located in very close binary systems (they are also called “contact”). In such places, a pair of bodies rotates at such a small distances that their gas shells touch and begin to mutually penetrate each other, as a result of which can occur strongest fluctuations in their luminosity in the visible part of the spectrum. To be maybe the same applies to the radio range?

Flashes of stars can often produce tremendous energy, and if radio bursts are generated inside our galaxy, their intensity may well be explained by just such a phenomenon. (Fig. Shutterstock.) To test this hypothesis, Avi Loeb and his colleagues turned to three quick sources radio bursts (funny as it seems, no one especially not involved). In general, a kind of surprise awaited the scientists. Although due brevity of events managed to find out the position of only part of the points from of which there was radio emission, it turned out that in at least one case the flash source was very close to the contact double a system where two sun-like stars revolve around a common center of mass (coarsening, “around each other”) in just 7.8 hours A star couple is located 2,600 light years from Earth. Of course, it’s absolutely accurate to determine whether a study comes from a certain stars or, say, from a farther partially blocked by it object, it is difficult, however, according to the calculations of astronomers, the probability of error does not exceed 5%, and this is impressive for physics and more or less tolerant of current astronomy.
