by Mysterious radio impulses come from place where scientists have never seen before.
For a decade, we have been sending us to us every two hours, about the Big Dipper constellation.
But working with several telescopes in these years has finally shown where they could come from. The long radio explosions seem to spend two dead stars, researchers believe.
Scientists believe that the two stars – a red dwarf and a white dwarf – are so firmly in circulation that their magnetic fields interact. If you collide every two hours, it sends out an explosion of radio signals.
Previously, astronomers had only persecuted radio impulses on neutron stars for so long. However, the new study suggests for the first time that they can also come from the movement of stars that are also connected in a binary system.
These impulses are short flashes of radio signals that can take between seconds and minutes. They resemble – but somewhat differently – fast radio bursts, a similar phenomenon that fascinates astronomers and still remains mysterious.
“The radio impulses are very similar for FrBs, but they each have different lengths,” said Kilpatrick. “The impulses have much lower energies than FRBs and usually last a few seconds, unlike FRBS, hold milliseconds. There is still an important question whether there is a continuum of objects between long -term radio transs and FrBs or whether it is different populations. “
The work is described in a new paper, “Sporadic radio impulses from a white dwarf binäran of the orbital period”, published in the magazine Natural astronomy.
