Hydrodynamic simulations of WD-WD mergers and the origin of RCB stars
Sagiv Shiber, Orsola De Marco, Patrick M. Motl +10
We study the properties of double white dwarf (DWD) mergers by performing hydrodynamic simulations using the new and improved adaptive mesh refinement code Octo-Tiger. We follow th…
Octo-Tiger: A New, 3D Hydrodynamic Code for Stellar Mergers that uses HPX Parallelisation
Dominic C. Marcello, Sagiv Shiber, Orsola De Marco +5
OCTO-TIGER is an astrophysics code to simulate the evolution of self-gravitating and rotat-ing systems of arbitrary geometry based on the fast multipole method, using adaptive mesh…
Numerical Simulations of Mass Transfer in Binaries with Bipolytropic Components
Kundan Kadam, Patrick M. Motl, Dominic C. Marcello +2
We present the first self-consistent, three dimensional study of hydrodynamic simulations of mass transfer in binary systems with bipolytropic (composite polytropic) components. In…
The role of dredge-up in double white dwarf mergers
Jan E. Staff, Brandon Wiggins, Dominic Marcello +6
We present the results of an investigation of the dredge-up and mixing during the merger of two white dwarfs with different chemical compositions by conducting hydrodynamic simulat…
A Numerical Method for Generating Rapidly Rotating Bipolytropic Structures in Equilibrium
Kundan Kadam, Patrick M. Motl, Juhan Frank +2
We demonstrate that rapidly rotating bipolytropic (composite polytropic) stars and toroidal disks can be obtained using Hachisu's self consistent field technique. The core and the…
A Comparison of Grid-Based and SPH Binary Mass-Transfer and Merger Simulations
Patrick M Motl, Juhan Frank, Jan Staff +5
Currently there is great interest in the outcomes and astrophysical implications of mergers of double degenerate binaries. In a commonly adopted approximation, the components of su…
