Numerical solutions of partial differential equations enable a broad range of scientific
research. The Dedalus project is a flexible, open-source, parallelized computational …

The extent of mixed regions around convective zones is one of the biggest uncertainties in
stellar evolution. One-dimensional overshooting descriptions introduce a free parameter (f …

The Tayler instability is an important but poorly studied magnetohydrodynamic (MHD)
instability that likely operates in stellar interiors. The non-linear saturation of the Tayler …

We present three-dimensional direct numerical simulations of internal waves excited by
turbulent convection in a self-consistent, Boussinesq and Cartesian model of mixed …

The presence of stable stratification has broad implications for the thermal and
compositional state of the outer core, the evolution of Earth's deep interior, and the …

Recent photometric observations of massive stars show ubiquitous low-frequency 'red
noise'variability, which has been interpreted as internal gravity waves (IGWs). Simulations of …

The quasibiennial oscillation (QBO) of equatorial winds on Earth is the clearest example of
the spontaneous emergence of a periodic phenomenon in geophysical fluids. In recent …

Internal gravity waves (IGW) propagate in the radiation zones of all stars. During
propagation, their amplitudes are affected by two main features: radiative diffusion and …

In binaries composed of either early-type stars or white dwarfs, the dominant tidal process
involves the excitation of internal gravity waves (IGWs), which propagate towards the stellar …
