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 ...

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.” ...

During the common-envelope phase, the progenitor of the M 33 X-7 black hole must have lost a large amount of mass for the two objects to be so close; but on the other hand, it must have retained ...
