But in common envelope evolution, “the companion star is so large that its outer layers engulf the neutron star as well,” Lorimer said. “This acts as a brake on the whole binary system.” ...

Astronomers detect new eclipsing post-common-envelope binary. Aug 15, 2022. Dancing stars and black holes in a cosmic cloud of gas: New research of the 'common envelope phase' Jun 16, 2020.

The team discovered a tight binary star surrounded by an expanding shell of material. This shell is matter is leftover from a stage in the stars' evolution called the common envelope phase. This ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such ...

If the binary is separated by less than 500 times the width of the sun, the companion star of the red giant becomes embedded within its extended, tenuous layers, hence the phrase "common envelope." ...

Astronomers may have discovered a rare type of binary star system, ... The pulsar would have then started siphoning off its companion's outer layers, forming a common envelope around them both.

That common envelope, the team notes, ... More information: Z. L. Yang et al, A pulsar-helium star compact binary system formed by common envelope evolution, Science (2025).
