Thermal instability analysis in the presence of a rotation and a magnetic field. Gravity vector parallel to the magnetic field vector ( ). Rotation vector at different values of . The dependence of the Rayleigh number ( ) for the onset of instability on the wave number ( ) when and (for free surfaces). and . Left panel: (continuous line), (dashed line), (dotted line), and (dotted-dashed line). Right panel: (curve labelled a), (curve labelled b), and (curve labelled c).
