Thermal convection is one of the main mechanisms of heat transport and mixing in stars in general and also in the photospheric layers which emit the radiation that we observe with astronomical instruments. The present lecture notes first introduce the role of convection in astrophysics and explain the basic physics of convection. This is followed by an overview on the modelling of convection. Challenges and pitfalls in numerical simulation based modelling are discussed subsequently. Finally, a…

Variable Density Flows in Rotating Astrophysical Plasma. Linear Waves and Resonant Phenomena

New observational data and modeling of physical processes constantly appear in the young and rapidly developing branch of science of plasma astrophysics. However, there is a lack of theoretical



Simulations of stellar convection, pulsation and semiconvection

Abstract We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations. Then, we turn

Stellar Evolution with a Variable Mixing-Length Parameter

By simulating the convection in the upper layers of seven diierent stars and matching these simulations to 1D mixing-length models using the same input physics, we have been able to infer the

Stellar Structure and Evolution

This book introduces the theory of the internal structure of stars and their evolution in time. It presents the basic physics of stellar interiors, methods for solving the underlying equations, and

Turbulence in Fluids

The seminar gives an introduction to turbulent motions of incompressible fluids. Due to the nature of the subject, most of the explanations are qualitative, although references to the actual

Foundations of Radiation Hydrodynamics

Exposes the great foundation-stones of research on radiating flows in astrophysics. Upon them are built the walls of methodology (some understandably incomplete). Concentration is on fundamentals but

Abstract We discuss some benefits and pitfalls when combining conceptually different types of closure approximations into complete Reynolds stress models of stellar convection.
