When white dwarfs—the hot remnants of stars like our sun—are orbited closely by another star, they sometimes steal mass away ...

hydrodynamic moving-mesh simulations of the common envelope phase in binary stellar systems. The Astrophysical Journal , 2015; 816 (1): L9 DOI: 10.3847/2041-8205/816/1/L9 Cite This Page : ...

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 ...

Only a few dozen of these short-lived binaries exist in the galaxy at a time, making the serendipitous find extremely ...

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 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 ...

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.

Now, however, some researchers are suggesting that a common-envelope binary star is the best way of explaining an object they've imaged. An observation-based model.

Through the project, titled “Brief But Spectacular: New Windows into the Physics of Common Envelope Evolution,” Nordhaus and his team will be conducting an observational survey of all galactic star ...
