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.

Common Envelope Evolution Leading to Supernovae with Dense Interaction [PDF]
The Astrophysical Journal, 2012 A variety of supernova events, including Type IIn supernovae and ultraluminous supernovae, appear to have lost up to solar masses of their envelopes in 10's to 100's of years leading up to the explosion.

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.

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-

An observational test of common-envelope evolution [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 By analysing and modelling the change in the abundance ratio of $^{12}$C/$^{13}$C and $^{16}$O/$^{17}$O on the surface of the lower mass star of a binary during the common-envelope (CE) phase of evolution, we propose a simple observational test of the CE

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.
