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…
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…
The jet feedback mechanism (JFM): from supernovae to clusters of galaxies
Noam Soker, Muhammad Akashi, Avishai Gilkis +4
We study the similarities of jet-medium interactions in several quite different astrophysical systems using 2D and 3D hydrodynamical numerical simulations, and find many similariti…
