A convection zone dynamo including the effects of magnetic buoyancy and downward flows
L. H. Li, S. Sofia
A magnetic flux tube may be considered both as a separate body and as a confined field. As a field, it is affected both by the cyclonic convection (-effect) and differential rot…
The effect of turbulent pressure on the p-mode frequencies in stellar models
P. Demarque, L. H. Li, F. J. Robinson +4
We have constructed models for the sun at three stages of its evolution: a zero-age main sequence model, the present sun, and a subgiant model. For each model, the turbulent pressu…
Irradiance or luminosity changes?
Sabatino Sofia, Linghuai H. Li
Whereas a variation of the solar luminosity, L, will inevitably cause a similar change of the total solar irradiance, S, the opposite is not true. In fact, the bulk of the days to…
Modelling of Shallow and Inefficient Convection in the Outer Layers of the Sun Using Realistic Physics
Yong -Cheol Kim, Peter A. Fox, Sabatino Sofia +1
In an attempt to understand the properties of convective energy transport in the solar convection zone, a numerical model has been constructed for turbulent flows in a compressible…
