Oscillatory convection in flux tubes, pores and sunspots.
Abstract
High-resolution images of the solar surface provide a means for probing sub-photospheric structures. The authors combine simple conceptual arguments with numerical models to consider the different flow regimes possible within flux tubes, pores and sunspots which should be found in detailed observations. In the presence of a strong magnetic field convection near the photosphere is likely to be oscillatory. The authors have carried out a series of numerical experiments involving simple atmospheres (polytropic in the absence of convection).
