Recently, astronomers in China proposed a new magnetic braking model, which revealed the dynamic feedback mechanism of mutual influence between low-quality X-ray binaries, and provided new ideas for explaining the evolutionary diversity of such celestial bodies. The relevant results were published in the international academic journal “Science Bulletin”. Low-mass X-ray binaries usually consist of a neutron star and a lesser mass companion star. Neutron stars have a strong gravitational pull and can attract matter on the surface of the companion star. When matter falls on a neutron star, it releases a large amount of energy due to intense motion and friction, producing bright X-rays. It's not easy for this “partner” to get along with. As matter transfers and orbital changes, some binaries continue to emit X-rays, while others explode intermittently. These binaries evolve into millisecond pulsar binaries with a wide orbital period distribution. How to explain these different evolutionary phenomena has always been a difficult problem in astronomical research. In response to the above problems, the research team proposed a new magnetic braking model, or brake model, which in turn solved the mystery of the evolution of low-quality X-ray binaries. The first author of the paper, Deng Zhuling, a postdoctoral fellow at the Yunnan Observatory of the Chinese Academy of Sciences, explained that in this model, the two stars are not separate from each other, but rather influence each other; they are a combination of interactions with each other. The accreted matter of the neutron star emits high-energy radiation. This radiation heats the companion star, making the companion star's star wind more intense. As the star wind increases, magnetic braking will naturally be greatly strengthened. This strengthening will reach saturation when supereddington is accumulated, and there will be no infinite positive cycle.
