(Left) Evolution of bubble radius R(t) (left axis) and expansion velocity V(t) (right axis) based on Equation (2). The red solid, blue dashed, and green dotted lines represent the lower limit (L_w = 1.6 × 10⁴³ erg s⁻¹, n_e = 0.01 cm⁻³) and cases where L_w/ρ₀ is increased by factors of 10 and 100, respectively. Symbols indicate the expected values at a jet age of 3 Myr, as denoted by the vertical line. (Right) Destruction timescales of molecular clouds as a function of cloud radius. The red solid and blue dashed lines represent the timescales for KH instability (t_KHI) and cloud ablation (t_abl), respectively. The green dotted and purple dotted–dashed lines correspond to classical and saturated thermal conduction timescales. The horizontal black line indicates the jet age of 3 Myr. The intersection of this reference line with each timescale defines the maximum cloud size that can be fully disrupted within the jet’s lifetime.
