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…
Solving the Riemann Problem for Realistic Astrophysical Fluids
Zhuo Chen, Matthew S. B. Coleman, Eric G. Blackman +1
We present new methods to solve the Riemann problem both exactly and approximately for general equations of state (EoS) to facilitate realistic modeling and understanding of astrop…
Accretion in Common Envelope Evolution
Luke Chamandy, Adam Frank, Eric G. Blackman +6
Common envelope evolution (CEE) occurs in some binary systems involving asymptotic giant branch (AGB) or red giant branch (RGB) stars, and understanding this process is crucial for…
Planetary Nebulae Shaped By Common Envelope Evolution
Adam Frank, Zhuo Chen, Thomas Reichardt +3
The morphologies of planetary nebula have long been believed to be due to wind shaping processes in which a fast wind from the central star impacts a previously ejected envelope. A…
Accretion in common envelope evolution
Luke Chamandy, Adam Frank, Eric G. Blackman +6
Common envelope evolution (CEE) is presently a poorly understood, yet critical, process in binary stellar evolution. Characterizing the full 3D dynamics of CEE is difficult in part…
