Athena++
Over the past year I have been using the Athena++ magnetohydrodynamics code. I perform 3D hydrodynamical simulations of supernova ejecta interacting with companion stars. I have experience with the adapative mesh refinement, MPI parallelization, multigrid self-gravity, and passive scalar features. Most recently I have started using the general equation-of-state capability. I input the MESA equation of state into Athena++ to allow for the effects of electron degeneracy, radiation, and Coulomb interactions.
Modules for Experiments in Stellar Astrophysics (MESA)
MESA is an open-source 1D stellar evolution code. I have been a long-term MESA user since 2017. I mainly use the MESA binary module to model white dwarfs in a binary, and occasionally I use the equation of state module and the opacity module independently, as well as the GYRE pulsations code. I have been a teaching assistant at MESA summer schools 2018, 2019, 2021, 2022, and MESA@Konkoly 2023, where we design hands-on labs for participants to apply MESA to various stellar evolution problems. In 2024 I lectured for MESA Down Under in Sydney, Australia. Our lab is about double white dwarf binaries, and you can find our materials here.
