In this work we report theoretical and numerical results on convection
in a viscoelastic binary mixture under rotation. In particular, we focus in the
Maxwelian case of viscoelastic fluid. We obtain explicit expressions for the convective
thresholds in terms of the mixture parameters of the system in the case
of idealized boundary conditions. We also calculate numerically the convective
thresholds for the case of realistic rigid-rigid boundary conditions.
