Final common envelope ejection by migration and jets
@article{Soker2014FinalCE, title={Final common envelope ejection by migration and jets}, author={Noam Soker}, journal={arXiv: Solar and Stellar Astrophysics}, year={2014} }
I summarize recent analytical and numerical studies of the common envelope (CE) process and suggest to replace the commonly used alpha-prescription for the CE ejection by a prescription based on final migration and jets launched by the companion or the core of the giant stellar primary. In the migration process the core-companion binary systems is surrounded by a highly oblate (flatten) envelope, a thick circumbinary disk, formed by the large angular momentum transferred from the core-companion…

Common envelope (CE) is an important phase in the evolution of many binary systems. Giant star / compact object interaction in binaries plays an important role in high-energy phenomena as well as in…
Energizing the last phase of common-envelope removal

We propose a scenario where a companion that is about to exit a common envelope evolution (CEE) with a giant star accretes mass from the remaining envelope outside its deep orbit and launches jets…

The evolution and physics of the common envelope (CE) phase are still not well understood. Jets launched from a compact object during this stage may define the evolutionary outcome of the binary…
CLOSE STELLAR BINARY SYSTEMS BY GRAZING ENVELOPE EVOLUTION
- Physics

I suggest a spiral-in process in which a stellar companion grazes the envelope of a giant star while both the orbital separation and the giant radius shrink simultaneously, forming a close binary…
Energy transport by convection in the common envelope evolution

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 recombination energy of…
Simulating the onset of grazing envelope evolution of binary stars

We present the first three-dimensional gas-dynamical simulations of the grazing envelope evolution (GEE) of stars, with the goal of exploring the basic flow properties and the role of jets at the…
Launching jets from accretion belts
- Physics

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 the accreting…
Neutron Star - Core Merger as a Rare R-process Site

We raise the possibility that strong r-process nucleosynthesis occurs inside jets launched by a neutron star (NS) spiraling-in inside the core of a red supergiant star. The strong r-process is the…
Forming equatorial rings around dying stars
- Physics

We suggest that clumpy-dense outflowing equatorial rings around evolved giant stars, such as in supernova 1987A and the Necklace planetary nebula, are formed by bipolar jets that compress gas toward…

Virtually all close compact binary stars are formed through common-envelope (CE) evolution. It is generally accepted that during this crucial evolutionary phase a fraction of the orbital energy is…
