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…
Understanding the Drag Torque in Common Envelope Evolution
Soumik Bhattacharyya, Luke Chamandy, Eric G. Blackman +2
Common envelope (CE) evolution is largely governed by the drag torque applied on the in-spiralling stellar components by the envelope. Previous work has shown that idealized models…
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…
Models of the Mass-Ejection Histories of pre Planetary Nebulae, IV. Magnetized Winds and the Origins of Jets, Bullets, and FLIERs
Bruce Balick, Adam Frank, Baowei Liu
The influences and consequences of toroidal magnetic fields in shaping the visible lobes of pre planetary nebulae ("prePNe") are explored in this, the last of a series of papers of…
Hydrodynamic and Magnetohydrodynamic Simulations of Wire Turbulence
Erica Fogerty, Baowei Liu, Adam Frank +2
We report on simulations of laboratory experiments in which magnetized supersonic flows are driven through a wire mesh. The goal of the study was to investigate the ability of such…
Models of the Mass-Ejection Histories of pre Planetary Nebulae, III. The Shaping of Lobes by post-AGB Winds
B. Balick, A. Frank, B. Liu
We develop a physical framework for interpreting high-resolution images of pre planetary nebule ("prePNe") with pairs of candle shaped lobes. We use hydrodynamical models to infer…
Energy Budget and Core-Envelope Motion in Common Envelope Evolution
Luke Chamandy, Yisheng Tu, Eric G. Blackman +4
We analyze a 3D hydrodynamic simulation of common envelope evolution to understand how energy is transferred between various forms and whether theory and simulation are mutually co…
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…
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…
Models of the Mass-Ejection Histories of pre Planetary Nebulae. II. The Formation of the Butterfly and its Proboscis in M2-9
Bruce Balick, Adam Frank, Baowei Liu +1
M2-9, or the "Butterfly Nebula" is one of the most iconic outflow sources from an evolved star. In this paper we present a hydrodynamic model of M2-9 in which the nebula is formed…
Models of the Hydrodynamic Histories of post-AGB Stars. I. Multiflow Shaping of OH231.8+04.2
Bruce Balick, Adam Frank, Baowei Liu +1
We present a detailed hydrodynamic model that matches the present structure of the well-observed preplanetary nebula OH231.8+04.2. The purpose of the model is to present a physical…
Hot planetary winds near a star: dynamics, wind-wind interactions, and observational signatures
Jonathan Carroll-Nellenback, Adam Frank, Baowei Liu +3
Signatures of "evaporative" winds from exo-planets on short (hot) orbits around their host star have been observed in a number of systems. In this paper we present global AMR simul…
