The researchers observed the repeated rapid FM201124A radio splash and recorded some 1,863 flashes, so they obtained the world ' s largest sample of FRB polarization observations. This was made possible by FAST, a spherical radio telescope with a 500-metre aperture, and the world ' s largest single-scenes and most sensitive radio telescope developed in China.
According to a study, the FRB 20201124A may be analog of pulse radiation from a galactic dual system of PSR B1259-63/LS 2883 containing PSR B1259-63 and Ve star LS 2883.
Rapid radioshots are single radio telescopes registered for several milliseconds of unknown nature, typical surge energy, assuming radiation isotrotropicity, equivalent to the release into outer space of energy released by the sun within a few days.
Although hundreds of FRBs have been discovered, their physical nature remains unclear.
In a new study, scientists presented a physical model that explained the observed characteristics of FRB 20201124A. They assumed that a repeated signal came from a dual system containing a magnet and a Ve star with a decretion disc.
Remember, Be-stars are very hot objects of spectrum class B with an effective temperature of between 10,000 and 30,000 K and the luminous intensity of class III to V. Their spectrum shows at least one emission line, usually the Balmer series of hydrogen.
A study by researchers from the National Astronomical Observatory of China and the University of Beijing was published in the international academic journal Nature.
