Bridging the gap between stars and planets
Aina Palau, Dimitris Stamatellos, Matthew Bate +58
The formation mechanisms of brown dwarfs (BDs) and free-floating planets (FFPs) are poorly constrained. The two main competing scenarios include the star-like scenario, where these…
Systematic Comparison between Constrained Transport and Mixed Divergence Cleaning Methods for Astrophysical Magnetohydrodynamic Simulations
Kengo Tomida, Kenji Eric Sadanari, Shinsuke Takasao +1
Magnetohydrodynamic (MHD) simulations are indispensable research infrastructure in astrophysics today. In order to satisfy the solenoidal constraint of the MHD equations on discret…
The Athena++ Adaptive Mesh Refinement Framework: Multigrid Solvers for Self-Gravity
Kengo Tomida, James M. Stone
We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-…
Optab: Public code for generating gas opacity tables for radiation hydrodynamics simulations
Shigenobu Hirose, Peter Hauschildt, Takashi Minoshima +2
We have developed a public code, Optab, that outputs Rosseland, Planck, and two-temperature Planck mean gas opacity tables for radiation hydrodynamics simulations in astrophysics.…
The Athena++ Adaptive Mesh Refinement Framework: Design and Magnetohydrodynamic Solvers
James M. Stone, Kengo Tomida, Christopher J. White +1
The design and implementation of a new framework for adaptive mesh refinement (AMR) calculations is described. It is intended primarily for applications in astrophysical fluid dyna…
