T and Σ variability for the model with μ = 0.6 for a typical IMBH accretion disk. The models present a strongly developed instability, leading to huge outbursts. Parameters: M = 3 × 10⁴M_⊙, α = 0.02, and ṁ = 0.25 for the radius cm. The red curve represents the stationary solution and the green dots show local values of the temperature and density in the dynamical model. The points occupy both the upper and lower branches of the S-curve. Green points represent the most common states of the disk, while blue vectors represent directions of the most common rapid changes of local T and Σ.
