Notes:
New results concerning the problem of surface-tension-driven instability in a rotating spherical fluid shell are presented. The fluid layer is assumed to be Boussinesq-like, heated from the inner sphere and placed in a microgravity environment (Marangoni problem). Small-amplitude disturbances are considered and the normal mode problem is solved numerically by means of a finite difference technique. Marginal stability curves are computed and surstability is exhibited. Onset of convection is subordinated to several parameters like the thickness of the layer, its angular velocity, and its viscous and diffusive properties; all these effects receive a special treatment.
