Description:

Many stellar environments in the Universe are dominated by (radiation)-hydrodynamical phenomena, that can be studied and modelled only keeping into account their multi-dimensional nature. Accurate observations and simulations of these phenomena are crucial for correct explanations and predictions in a wide range of Astrophysical fields. The focus of this session is the accurate description of inherently multi-dimensional (radiation)-hydrodynamical processes which play a critical role in stellar objects from early to advanced stages of evolution, including stellar remnants. Such processes are at the core of many open questions in stellar astrophysics including (i) turbulent convection, convective overshooting, and boundary mixing; (ii) internal waves: excitation mechanisms, transport properties and observable signatures; (iii) rotation and angular momentum transport; (iv) accretion onto white dwarfs; (v) relating results from multi-dimensional simulations to 1D models and observations. We encourage submissions based on observations, models, and simulations discussing new results and current challenges in this field. We invite contributions from researchers at all career stages, as we aim to bring together experts from the full spectrum of stellar fluid dynamics to stimulate discussions, exchange ideas and learn from each other.
