Methods for Simulating the Heavy Core Instability

Methods for Simulating the Heavy Core Instability

Vortices have been proposed as the sites of planet formation, where dust collects and grows into planetesimals, the building blocks of planets. However, for very small dust particles that can be treated as a pressure-less fluid, we have recently discovered the “heavy core” instability, driven by...
