Common envelope evolution of eccentric binaries [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Common envelope evolution (CEE) is believed to be an important stage in the evolution of binary/multiple stellar systems. Following this stage, the CE is thought to be ejected, leaving behind a compact binary (or a merger product).

Accretion in common envelope evolution [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
AbstractCommon envelope evolution (CEE) occurs in some binary systems involving asymptotic giant branch (AGB) or red giant branch (RGB) stars, and understanding this process is crucial for understanding the origins of various transient phenomena. CEE has been shown to be highly asymmetrical and global 3D simulations are needed to help understand the ...

Lessons from the Ionised and Molecular Mass of Post-CE PNe

open access: yesGalaxies, 2022
Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to ...

Common envelope evolution on a moving mesh [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
AbstractWe outline the methodology of simulating common envelope evolution (CEE) with the moving-mesh code manga. We extend manga to include multiple time-steps. This provides substantial speedups for problems with large dynamic range. We describe the implementation of realistic equations of state relevant in stellar structure and the generation of ...

Energy budget and core-envelope motion in common envelope evolution [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
We analyze a 3D hydrodynamic simulation of common envelope evolution to understand how energy is transferred between various forms and whether theory and simulation are mutually consistent given the setup. Virtually all of the envelope unbinding in the simulation occurs before the end of the rapid plunge-in phase, here defined to coincide with the ...

Long-term Evolution of Massive-star Post-common-envelope Circumbinary Disks and the Environments of Fast Luminous Transients

open access: yesThe Astrophysical Journal, 2023
If the envelope of a massive star is not entirely removed during common envelope (CE) interaction with an orbiting compact (e.g., black hole (BH) or neutron star (NS)) companion, the residual bound material eventually cools, forming a centrifugally ...

SCATTER: A New Common Envelope Formalism

open access: yesThe Astrophysical Journal, 2023
One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them. Interactions between the stars and the envelope shrinks the orbit.

Common envelope evolution of binary stars [PDF]

open access: yesSpace Science Reviews, 1989
AbstractWe discuss the common envelope phase in the evolution of binary systems. The problem of the efficiency of energy deposition into envelope ejection is treated in some detail. We describe the implications of common envelope evolution for the shaping of planetary nebulae with close binary nuclei and for double white dwarf systems, considered to be
