Common envelope binary interaction simulations between a thermally pulsating AGB star and a low mass companion. [PDF]
Mon Not R Astron Soc, 2022 ABSTRACT At least one in five of all planetary nebulae are the product of a common envelope (CE) interaction, where the companion in-spirals into the envelope of an asymptotic giant branch (AGB) star ejecting the nebula and leaving behind a compact binary. In this work we carry out 3D smoothed particle hydrodynamics simulations of the CE

Modeling High Mass X-Ray Binaries to Double Neutron Stars through Common Envelope Evolution
The Astrophysical JournalWe present detailed evolutionary simulations of wide binary systems with high-mass (8–20 M _⊙ ) donor stars and a 1.4 M _⊙ neutron star. Mass transfer in such binaries is dynamically unstable, and common envelope (CE) evolution is followed.

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).

The post-common-envelope binary central star of the planetary nebula ETHOS 1 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We present a detailed study of the binary central star of the planetary nebula ETHOS 1 (PN G068.1+11.0). Simultaneous modelling of light and radial velocity curves reveals the binary to comprise a hot and massive pre-white dwarf with an M-type main-sequence companion.

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.

Bipolar planetary nebulae from common-envelope evolution of binary stars
Astronomy & Astrophysics, 2022 Asymmetric shapes and evidence for binary central stars suggest a common-envelope origin for many bipolar planetary nebulae. The bipolar components of the nebulae are observed to expand faster than the rest, and the more slowly expanding material has been associated with the bulk of the envelope ejected during the common-envelope phase of a stellar ...

Simulating the Outcome of a Binary Neutron Star Merger in a Common Envelope Jets Supernova [PDF]
The Astrophysical Journal, 2021 Abstract We simulate the influence of the energy that the merger process of two neutron stars (NSs) releases inside a red supergiant (RSG) star on the RSG envelope inner to the merger location. In the triple-star common envelope evolution (CEE) that we consider, a tight binary system of two NSs spiraling in inside an RSG envelope and ...

A Common Envelope Binary Star Origin of Long Gamma-ray Bursts [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 The stellar origin of gamma-ray bursts can be explained by the rapid release of energy in a highly collimated, extremely relativistic jet. This in turn appears to require a rapidly spinning highly magnetised stellar core that collapses into a magnetic neutron star or a black hole within a relatively massive envelope.
