Solar Models with Convective Overshootopacity tables by tables from Lawrence Livermore. For the calculated models the thickness lies between 0.13 and 0.19 of a pressure scale height. We also propose a model with a smoothed transition from the overshoot layer to the radiative core, obtained by a limitation of the temperature excess of the convection eddies.

Photospheric Downflows: How Deep, How Coherent, How Important?at plume initiation by rapidly localized cooling results in both monopolar and dipolar acoustic emission. The mechanism is distinct in that pressure fluctuations are induced thermodynamically by radiative loss as well as dynamically by fluid motion.

Convective Overshooting and Mixingerical simulation, and the new tools of helio- and asteroseismology. Other mixing processes that may affect the evolution of the sun and stars are also discussed, as is the possible effect of mixing on the solar neutrino problem.

A Calibration of Mixing Length Theory Based on RHD Simulations of Solar-Type Convectionh theory (MLT), s is translated to an effective mixing-length parameter (..) appropriate to construct global stellar models. The calibration based on our present set of 2D RHD models shows a moderate variation of .. across the domain of the HRD investigated so far.

A Precision-Controlled Solar Model with Realistic Subatmospheric Stratificationry conditions at τ ≈ 20 have been implemented. In addition, a spatially variable mixing length has been employed to reproduce the T-P-stratification of the outer convective layers as calculated by 2D-hydrodynamical models. We find that the changes in the subatmospheric regions lead to a further improvement of the solar model.

Compressible Turbulence′, .″ and ρ′ are related by a poly trope. Thus, there is only one free parameter, the polytropic index .. This can be contrasted with the incompressible treatments which contain several adjustable parameters.
