Simulating the convection in red super-giant stars: wobbling jets in common envelope evolution
Shlomi Hillel, Ron Schreier, Noam Soker
We use our newly constructed three-dimensional red supergiant (RSG) stellar model, which also mimics nuclear energy production and photospheric emission, to calculate the stochasti…
Building three-dimensional giant stellar models for common envelope simulations
Ron Schreier, Shlomi Hillel, Noam Soker
We build a three-dimensional (3D) red supergiant (RSG) stellar model by transporting a 1D stellar model to a 3D numerical grid, mimicking core nuclear power by depositing energy in…
Forming a clumpy circumstellar material in energetic pre-supernova activity
Shlomi Hillel, Ron Schreier, Noam Soker
We demonstrate by three-dimensional hydrodynamical simulations of energy deposition into the envelope of a red supergiant (RSG) model the inflation of a Rayleigh-Taylor unstable en…
Jet-shaped filamentary ejecta in common envelope evolution
Ron Schreier, Shlomi Hillel, Noam Soker
We conduct three-dimensional (3D) hydrodynamical simulations of common envelope evolution (CEE) of a neutron star (NS) that launches jets as it spirals in inside the envelope of a…
Jet-powered turbulence in common envelope evolution
Shlomi Hillel, Ron Schreier, Noam Soker
We conduct a three-dimensional hydrodynamical simulation of a common envelope evolution (CEE) where a neutron star (NS) spirals-in inside the envelope of a red supergiant (RSG) sta…
Simulating the deposition of angular momentum by jets in common envelope evolution
Ron Schreier, Shlomi Hillel, Noam Soker
We conducted three-dimensional hydrodynamical simulations of common envelope evolution (CEE) of a neutron star (NS) or a black hole (BH) inside a red supergiant (RSG) envelope and…
The response of a red supergiant to a common envelope jets supernova (CEJSN) impostor event
Nitzan Ragoler, Ealeal Bear, Ron Schreier +2
Using a one-dimensional stellar evolution code we simulate the response of a red supergiant (RSG) star to injection of energy and to mass removal. We take the values of the energy…
Three-dimensional simulations of the jet feedback mechanism in common envelope jets supernova
Shlomi Hillel, Ron Schreier, Noam Soker
We conduct three-dimensional hydrodynamical simulations of common envelope jets supernova (CEJSN) events where we assume that a neutron star (NS) launches jets as it orbits inside…
Simulating highly-eccentric common envelope jets supernova (CEJSN) impostors
Ron Schreier, Shlomi Hillel, Sagiv Shiber +1
We conduct three-dimensional hydrodynamical simulations of eccentric common envelope jets supernova (CEJSN) impostors, i.e., a neutron star (NS) that crosses through the envelope o…
A companion star launching jets in the wind acceleration zone of a giant star
Shlomi Hillel, Ron Schreier, Noam Soker
By conducting three-dimensional (3D) hydrodynamical simulations we find that jets that a main sequence companion launches as it orbits inside the wind acceleration zone of an asymp…
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…
Energy transport by convection in the common envelope evolution
Efrat Sabach, Shlomi Hillel, Ron Schreier +1
We argue that outward transport of energy by convection and photon diffusion in a common envelope evolution (CEE) of giant stars substantially reduces the fraction of the recombina…
An outburst powered by the merging of two stars inside the envelope of a giant
Shlomi Hillel, Ron Schreier, Noam Soker
We conduct three-dimensional hydrodynamical simulations of energy deposition into the envelope of a red giant star as a result of the merger of two close main sequence stars or bro…
Launching jets from accretion belts
Ron Schreier, Noam Soker
We propose that sub-Keplerian accretion belts around stars might launch jets. The sub-Keplerian inflow does not form a rotationally supported accretion disk, but it rather reaches…
Binary interactions with high accretion rates onto main sequence stars
Sagiv Shiber, Ron Schreier, Noam Soker
Energetic outflows from main sequence stars accreting mass at very high rates might account for the powering of some eruptive objects, such as merging main sequence stars, major er…
Three-dimensional simulations of the orientation and structure of reconnection X-lines
R. Schreier, M. Swisdak, J. F. Drake +1
This work employs Hall magnetohydrodynamic (MHD) simulations to study the X-lines formed during the reconnection of magnetic fields with differing strengths and orientations embedd…
