Effect of Neutron Star Jets on Common Envelope Evolution
Deepanshu Gurjar, Luke Chamandy, Eric G. Blackman +3
The common envelope (CE) phase is a key stage in binary star evolution that is still not very well understood. Once engulfed by the giant star, the binary companion may accrete env…
How negative feedback and the ambient environment limit the influence of recombination in common envelope evolution
Luke Chamandy, Jonathan Carroll-Nellenback, Eric G. Blackman +5
We perform 3D hydrodynamical simulations to study recombination and ionization during the common envelope (CE) phase of binary evolution, and develop techniques to track the ionic…
Bipolar Planetary Nebulae from Outflow Collimation by Common Envelope Evolution
Yangyuxin Zou, Adam Frank, Zhuo Chen +8
The morphology of bipolar planetary nebulae (PNe) can be attributed to interactions between a fast wind from the central engine and dense toroidal shaped ejecta left over from comm…
How Drag Force Evolves in Global Common Envelope Simulations
Luke Chamandy, Eric G. Blackman, Adam Frank +3
We compute the forces, torque and rate of work on the companion-core binary due to drag in global simulations of common envelope (CE) evolution for three different companion masses…
