For the first time, Chinese and Australian astronomers have discovered direct evidence for the evolution of the shared envelope of binary stars

This astronomical mystery, which has been proposed for nearly half a century, was recently revealed by astronomers from China and Australia. They cooperated to discover a binary star system that has just completed the ejection of a shared envelope.

The speed of km leaves the binary system. This is the first time that scientists have observed direct evidence for the evolution of the key process of the binary star’s shared envelope — the expanding shared envelope thrown into space by the binary star.

This important discovery will open up the academic community to accurately characterize the evolution process of the binary star’s shared envelope through astronomical observations, and open up an important research direction in astronomy.

This major discovery and research achievement in the field of astronomy was completed by the team of Academician Han Zhanwen of the Yunnan Observatory of the Chinese Academy of Sciences and the team of Chris Wolf of the Australian National University.

In the early morning of July 7th, Beijing time, the achievement paper was published in the international professional academic journal. The journal Monthly Notices of the Royal Astronomical Society is published online. The picture is an artistic image of the shared envelope of the binary star system ejected according to the professional results.
