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…

Comment on "A snapshot of the oldest AGN feedback phases"

Noam Soker, Shlomi Hillel

We dispute a very recent claim, which is based on new LOFAR radio observations, that mixing does not heat the intragroup medium of the galaxy group Nest200047. We argue to the cont…

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…

Uplifted cool gas and heating by mixing in cooling flows

Shlomi Hillel, Noam Soker

We analyze our earlier three-dimensional hydrodynamical numerical simulation of jet-inflated bubbles in cooling flow clusters, and find that dense gas that was not heated by the je…

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…
