Minimum value of the eigenvalue L at given Ξ, the dimensionless radius characterizing the system, as a function of Ξ, for the constant { E,V } case. When the minimum L is negative the system is unstable. The system becomes unstable at Ξ = 34.36, which corresponds to a density contrast ≃709, the same value obtained from the thermodynamical approach. From the figure we can read the typical time scale of the instability. As Ξ → ∞, the asymptotic value of L, L =  −0.042, is the same as for the other cases (see Figs. 2 and 4).
