Evolution of the disk parameters: radial velocity dispersion ⟨ σ_R1 ⟩, ⟨ σ_R2 ⟩, ⟨ σ_R ⟩ (first row), vertical velocity dispersion ⟨ σ_z1 ⟩, ⟨ σ_z2 ⟩, ⟨ σ_z ⟩ (second row), vertical-to-radial velocity dispersion ratio ⟨ σ_z1/σ_R1 ⟩, ⟨ σ_z2/σ_R2 ⟩, ⟨ σ_z/σ_R ⟩ (third row), and disk thickness ⟨ z₁ ⟩, ⟨ z₂ ⟩, ⟨ z ⟩ (bottom row); see Eqs. (4), (5). Blue circles correspond to the secondary (less massive) component, green crosses to the host component, and red squares represent the two-component averaged values. We recall that the two components in these models are co-rotating.
