Progress of Common Envelope Evolution [PDF]
Highlights of Astronomy, 1989 AbstractThe current understanding of the common envelope binary phase of evolution is presented. The results obtained from the detailed computations of the hydrodynamical evolution of this phase demonstrate that the deposition of energy by the double core via frictional processes is sufficiently rapid to drive a mass outflow, primarily in the ...

The binding energy parameter for common envelope evolution [PDF]
Research in Astronomy and Astrophysics, 2016 The binding energy parameter $ $ plays a vital role in common envelope evolution. Though it is well known that $ $ takes different values for stars with different masses and varies during stellar evolution, it has been erroneously adopted as a constant in most of the population synthesis calculations. We have systematically calculated the values of $

Criteria for Dynamical Timescale Mass Transfer of Metal-poor Intermediate-mass Stars
The Astrophysical Journal, 2023 The stability criteria of rapid mass transfer and common-envelope evolution are fundamental in binary star evolution. They determine the mass, mass ratio, and orbital distribution of many important systems, such as X-ray binaries, type Ia supernovae, and

Oxygen-neon-rich merger during common envelope evolution [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We conduct a population synthesis study of the common envelope evolution (CEE) of a white dwarf (WD) and an asymptotic giant branch (AGB) star and find that the potential number of type Ia supernovae (SNe Ia) from the core degenerate (CD) and from the double degenerate (DD) scenarios are of the same order of magnitude.

Parasite common envelope evolution by triple-star systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We study a scenario in which a giant wide tertiary star engulfs and forces a tight binary system of a white dwarf (WD) and a main-sequence (MS) star to enter a common envelope evolution (CEE) with each other, and then unbinds the WD–MS common envelope.

Common Envelope Evolution through Planetary Nebula Eyes
AIP Conference Proceedings, 2005 The common envelope interaction is responsible for evolved close binaries. Among them are a minority of central stars of planetary nebula (PN). Recent observational results, however, point to most PN actually being in binary systems. We therefore ask the question if it is feasible that most, or even all Galactic PN derive from a common envelope ...

Moving Boundaries in Common Envelope Evolution
Proceedings of the Wisconsin Space Conference, 2022 The common envelope phase in binary star systems is simulated using the 3-D moving-mesh hydrodynamic code MANGA. The companion object is modeled as a moving boundary condition in our simulations. We outline the methodology of implementing moving boundary conditions into MANGA, which are reactive to hydrodynamic and gravitational forces.
