Properties of self-excited pulsations in 3D simulations of AGB stars and red supergiants

Understand

The characteristic variability of cool giants and supergiants is attributed to a combination of stellar pulsation and large-scale convective flows.

• Full 3D radiation-hydrodynamical modelling is an essential tool for understanding the nature of these dynamical processes.
• The parameter space in our 3D model grid of red giants has expanded in recent years.
• These models can provide many insights on the nature and properties of the pulsations, including the interplay between convection and pulsations.
