PLASMA PHYSICS IN AN ASTROPHYSICAL ENVIRONMENT.
Abstract
Problems involving the stability and equilibrium of astrophysical systems have been investigated, particularly the structure of rotating turbulent convective zones and the effect of rotation of the shape of a star. It has been shown that the rotational interference with convection can produce an oblateness and drive meridional circulation which produces equatorial acceleration. The effect of circulation in the surface layers of the sun on the observed flux from equator and pole have shown that the results obtained by Dicke do not necessarily imply a large quadrupole moment for the sun. The deep ionisation zones to be expected in very large giants have been shown to give rise to dynamical instabilities leading to the ejection of large amounts of mass, as is observed in planetary nebulae.
