Wobbling Jets in Common Envelope Evolution
The Astrophysical Journal, 2023 We find that the convective motion in the envelopes of red supergiant (RSG) stars supplies a non-negligible stochastic angular momentum to the mass that a secondary star accretes in a common envelope evolution (CEE), such that jets that the secondary ...

Jet-powered Turbulence in Common Envelope Evolution
The Astrophysical Journal, 2023 We conduct a three-dimensional hydrodynamical simulation of common envelope evolution (CEE) where a neutron star (NS) spirals in inside the envelope of a red supergiant star in a predetermined orbit.

Planetary Nebulae Shaped by Common Envelope Evolution [PDF]
Galaxies, 2018 The morphologies of planetary nebula have long been believed to be due to wind shaping processes in which a “fast wind„ from the central star impacts a previously ejected envelope.

Post-AGB Discs from Common-Envelope Evolution [PDF]
Galaxies, 2018 Post-asymptotic giant branch (post-AGB) stars with discs are all binaries. Many of these binaries have orbital periods between 100 and 1000 days so cannot have avoided mass transfer between the AGB star and its companion, likely through a common-

Dusty Common Envelope Evolution
GalaxiesWe present the first hydrodynamical simulations of common envelope evolution that include the formation of dust and the effect of radiation pressure on dust grains.

Jet-shaped filamentary ejecta in common envelope evolution
The Open Journal of AstrophysicsWe conduct three-dimensional (3D) hydrodynamical simulations of common envelope evolution (CEE) of a neutron star (NS) that launches jets as it spirals in inside the envelope of a rotating red supergiant (RSG) stellar envelope and find that Rayleigh ...

The Evolution of Binaries Embedded Within Common Envelopes
The Astrophysical JournalTriple stellar systems allow us to study stellar processes that cannot be attained in binary stars. The evolutionary phases in which the stellar members undergo mass exchanges can alter the hierarchical layout of these systems.

Common envelope evolution [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractMany binary star systems are not wide enough to contain the progenitor stars from which they were made. One explanation for this is that when one star becomes a red giant a common envelope forms around both stars in the binary system. The core of the giant and its companion star continue to orbit one another inside the envelope.

Common envelope evolution of massive stars [PDF]
Proceedings of the International Astronomical Union, 2018 AbstractThe discovery via gravitational waves of binary black hole systems with total masses greater than 60Mʘ has raised interesting questions for stellar evolution theory. Among the most promising formation channels for these systems is one involving a common envelope binary containing a low metallicity, core helium burning star with mass ⁓30 – 40Mʘ ...
