On Instability of a Composite Rotating Stellar Atmosphere
Author:
Abstract: The aim of the present work was to study the thermal-convective instability of a composite rotating stellar atmosphere in the presence of a variable horizontal magnetic field to include, separately, the effects of medium permeability and solute gradient. Following the linearized stability theory, Boussinesq approximation and normal mode analysis, the dispersion is obtained in each case. The criteria for monotonic instability in each case have been obtained which generalize the Defouw’s criterion derived for thermal-convective instability in the absence of above effects.
