Astronomers From China, Australia tly Discover Binary System Ejecting Common Envelope 5ad3i

A team of astronomers from the Yunnan Observatories (YAO) of the Chinese Academy of Sciences and the Australian National University have tly discovered a binary system that is ejecting a common envelope. The scientists have managed to observe a common envelope evolution, which has long been thought to be a key step in binary star system formation, for the first time. Binary stars are systems where two stars orbit each other at a close distance. The observations were published in a research paper that was published in the Monthly Notices of the Royal Astronomical Society.

For the observations, the team of scientists from China and Australia took help from the Australian National University's 2.3-meter wide-field telescope and the stars in the recently found star system are orbiting each other within 3.5 hours, and are slowly getting closer with time.

Scientists have neutron stars.

In the case of J 1920, a successful ejection of the common envelope happened nearly 10,000 years ago. While scientist B. Paczynski had theorised about the common envelope in 1976, scientists had been unable to observe one before.
