Instabilities in the modelling of massive stars — •Cyril Georgy — Geneva Observatory, Geneva University, Geneva, Switzerland

In this review,I will discuss how instabilities are included in state-of-the-art stellar evolution codes. In particular, I will review the status of the modelling of convection and instabilities linked to rotation. I will highlight the uncertainties linked to this modelling and discuss how hydrodynamics simulations can help in improving our understanding of these instabilities.
