The Impact of Angular Momentum Loss on the Outcomes of Binary Mass Transfer
The Astrophysical Journal, 2023 We use the rapid binary population synthesis code COMPAS to investigate commonly used prescriptions for the determination of mass transfer stability in close binaries and the orbital separations after stable mass transfer.

The post-common-envelope binary central star of the planetary nebula Ou 5 [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou 5. Low-resolution spectra obtained during the primary eclipse - to our knowledge the first isolated spectra of the companion to a post-common-envelope planetary nebula central star - were compared to catalogue ...

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 ...

Post-common envelope binary stars, radiative levitation, and blue large-amplitude pulsators [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Following the recent discovery of a new class of pulsating star, the blue large-amplitude pulsators (BLAPs), pulsation stability analysis was carried out on evolutionary models of post-common envelope (CE) ejection stars of 0.3 and 0.46 solar masses.

A survey for post common-envelope binary stars using GALEX and SDSS photometry [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We report the first results of our programme to obtain multi-epoch radial velocity measurements of stars with a strong far-UV excess to identify post common-envelope binaries (PCEBs). The targets have been identified using optical photometry from SDSS DR4, ultraviolet photometry from GALEX GR2 and proper motion information from SDSS DR5.

SCATTER: A New Common Envelope Formalism
The 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.

Dust formation during the interaction of binary stars by common envelope
Proceedings of the International Astronomical Union, 2023 AbstractWe performed numerical simulations of the common envelope (CE) interaction between two intermediate-mass asymptotic giant branch (AGB) stars and their low-mass companions. For the first time, formation and growth of dust in the envelope is calculated explicitly.

Common envelope evolution of binary stars [PDF]
Space 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

Tidal dissipation impact on the eccentric onset of common envelope phases in massive binary star systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Tidal dissipation due to turbulent viscosity in the convective regions of giant stars plays an important role in shaping the orbits of pre-common-envelope systems. Such systems are possible sources of transients and close compact binary systems that will eventually merge and produce detectable gravitational wave signals.
