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.

Galaxies, 2018 The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

Planetary Nebulae Embryo after a Common Envelope Event
Galaxies, 2018 In the centers of some planetary nebulae are found close binary stars. The formation of those planetary nebulae was likely through a common envelope event, which transformed an initially-wide progenitor binary into the currently observed close binary ...

The planetary nebula IC 4776 and its post-common-envelope binary central star [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We present a detailed analysis of IC 4776, a planetary nebula displaying a morphology believed to be typical of central star binarity. The nebula is shown to comprise a compact hourglass-shaped central region and a pair of precessing jet-like structures.

Mergers via failed common envelope as a route toward intermediate-mass stripped stars
Astronomy & AstrophysicsStripped stars are a common product of binary stellar systems, spanning a wide mass range from Wolf-Rayet stars to hot subdwarfs and helium white dwarfs.

Physical Review D, 2022 We present a novel way of modeling common envelope evolution in binary and few-body systems. We consider the common envelope inspiral as driven by a drag force with a power-law dependence in relative distance and velocity. The orbital motion is resolved either by direct N-body integration or by solving the set of differential equations for the orbital ...

Binary neutron star merger in common envelope jets supernovae [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT I explore a triple-star scenario where a tight neutron star (NS)–NS binary system enters the envelope of a red supergiant (RSG) star and spirals-in towards its core. The two NSs accrete mass through accretion discs and launch jets that power a very luminous and long transient event, a common envelope jets supernova (CEJSN) event.

Are extreme asymptotic giant branch stars post-common envelope binaries? [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 ABSTRACT Modelling dust formation in single stars evolving through the carbon-star stage of the asymptotic giant branch (AGB) reproduces well the mid-infrared colours and magnitudes of most of the C-rich sources in the Large Magellanic Cloud (LMC), apart from a small subset of extremely red objects (EROs).
