  1. 1 Stellar convective penetration: Context, theory, and simulations
  2. 2 A simple model of a radiative-convective boundary
  3. 3 Convective overshoot causes entrainment.
  4. 4 Three linked processes in convective boundary mixing A fluid dynamical perspective
  5. 5 Entrainment builds a penetration zone
  6. 6 A toy model of fluxes in stellar convection
  7. 7 What sets the size of a convective penetration region?
  8. 8 A toy model of fluxes in convective penetration
  9. 9 Strong PZ dependence on P in simulations
  10. 10 From 3D to MESA
  11. 11 Wrap up We think we understand convective penetration, generally We think it's parameterizeable. We need to expand the model & nail down parameter values. Questions?
  12. 12 Dynamics of convective penetration
  13. 13 Measured output profiles of a simulation of penetration
