A red giant branch common envelope evolution scenario for the exoplanet WD 1856 b
Ariel Merlov, Ealeal Bear, Noam Soker
We propose a common envelope evolution (CEE) scenario where a red giant branch (RGB) star engulfs a planet during its core helium flash to explain the puzzling system WD 1856+534 w…
Rapid expansion of red giant stars during core helium flash by waves propagation to the envelope and implications to exoplanets
Ealeal Bear, Ariel Merlov, Yarden Arad +1
We assume that the strong convection during core helium flash of low mass red giant branch (RBG) stars excite waves that propagate to the envelope, and find that the energy that th…
Parasite common envelope evolution by triple-star systems
Noam Soker, Ealeal Bear
We study a scenario by 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 evol…
The future influence of six exoplanets on the envelope properties of their parent stars on the giant branches
Ivan Rapoport, Ealeal Bear, Noam Soker
We study the evolution of six exoplanetary systems with the stellar evolutionary code MESA and conclude that they will likely spin-up the envelope of their parent stars on the red…
Rare events of a peculiar thermonuclear supernova that precedes a core collapse supernova
Ealeal Bear, Noam Soker
We study stellar binary evolution that leads to the formation of a white dwarf (WD) that explodes in a thermonuclear supernova at the termination of a common envelope evolution (CE…
On the role of reduced wind mass-loss rate in enabling exoplanets to shape planetary nebulae
Ahlam Hegazi, Ealeal Bear, Noam Soker
We use the stellar evolution code MESA-binary and follow the evolution of three exoplanets and two brown dwarfs (BDs) to determine their potential role in the future evolution of t…
On rare core collapse supernovae inside planetary nebulae
Ealeal Bear, Noam Soker
We conduct simulations using MESA of the reverse formation of a white dwarf (WD)-neutron star (NS) binary system in which the WD forms before the NS. We conclude that a core collap…
Enhanced mass-loss rate evolution of stars with and missing optically-observed type II core-collapse supernovae
Roni Anna Gofman, Naomi Gluck, Noam Soker
We evolve stellar models with zero-age main sequence (ZAMS) mass of under the assumption that they experience an enhanced mass-loss rate when cros…
Jet-driven active galactic nucleus feedback in galaxy formation before black hole formation
Ealeal Bear, Noam Soker
We propose a scenario where during galaxy formation an active galactic nucleus (AGN) feedback mechanism starts before the formation of a supermassive black hole (SMBH). The superma…
Inclined jets inside a common envelope of a triple stellar system
Ron Schreier, Shlomi Hillel, Noam Soker
We conduct a three-dimensional hydrodynamical simulation to study the interaction of two opposite inclined jets inside the envelope of a giant star, and find that the jets induce m…
Variable jets at the termination of the common envelope evolution
Noam Soker
I propose that at the termination of the common envelope evolution (CEE) the companion to the giant star might launch jets that have variable directions and intensities, hence the…
The common envelope jets supernova (CEJSN) r-process scenario
Aldana Grichener, Noam Soker
We study r-process feasibility inside jets launched by a cold neutron star (NS) spiralling-in inside the core of a giant star, and find that such common envelope jets supernova eve…
The formation of `columns crowns' by jets interacting with a circumstellar dense shell
Muhammad Akashi, Noam Soker
We conduct three-dimensional hydrodynamical simulations of two opposite jets that interact with a spherical slow wind that includes a denser shell embedded within it, and obtain a…
Counteracting Tidal Circularization with the Grazing Envelope Evolution
Amit Kashi, Noam Soker
We show that substantially enhanced mass loss at periastron passages, as is expected in the grazing envelope evolution (GEE), can compensate for the circularization effect of the t…
Oxygen-neon rich merger during common envelope evolution
Pere Canals, Santiago Torres, Noam Soker
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…
The limited role of recombination energy in common envelope removal
Aldana Grichener, Efrat Sabach, Noam Soker
We calculate the outward energy transport time by convection and photon diffusion in an inflated common envelope and find this time to be shorter than the envelope expansion time.…
Radiating the hydrogen recombination energy during common envelope evolution
Noam Soker, Aldana Grichener, Efrat Sabach
By using the stellar evolution code MESA we show that most of the hydrogen recombination energy that is released as the envelope expands during a regular common envelope evolution…
Possible white dwarf progenitors of type Ia supernovae
Ealeal Bear, Noam Soker
We examine catalogs of white dwarfs (WDs) and find that there are sufficient number of massive WDs, M_WD > 1.35Mo, that might potentially explode as type Ia supernovae (SNe Ia) in…
The orientation of Eta Carinae and the powering mechanism of intermediate luminosity optical transients (ILOTs)
Amit Kashi, Noam Soker
Contrary to recent claims, we argue that the orientation of the massive binary system Eta Carinae is such that the secondary star is closer to us at periastron passage, and it is o…
Orbital radius during the grazing envelope evolution
Abedallah Abu-Backer, Avishai Gilkis, Noam Soker
We use the binary module of the MESA code to study the evolution of an evolved binary system where we assume that a main sequence companion removes the outskirts of the envelope of…
Forming H-shaped and barrel-shaped nebulae with interacting jets
Muhammad Akashi, Ealeal Bear, Noam Soker.
We conduct three-dimensional hydrodynamical simulations of two opposite jets launched from a binary stellar system into a previously ejected shell and show that the interaction can…
The Class of Jsolated Stars and Luminous Planetary Nebulae in old stellar populations
Efrat Sabach, Noam Soker
We suggest that stars whose angular momentum (J) does not increase by a companion, star or planet, along their post-main sequence evolution have much lower mass loss rates along th…
