Synthetic X-ray unabsorbed flux (erg cm⁻² s⁻¹) and luminosity (erg s⁻¹) plot of the Bubble Nebula as it evolves in time (Myr). Seven X-ray bands simulated from soft to hard X-rays, including 0.1 keV, 0.2 keV, 0.5 keV, 1 keV, 2 keV, 5 keV, and 10 keV. Solid lines are from the 1b simulation discussed in this paper, dashed lines are from a lower-resolution (N_zones = 768 × 512) simulation. Mechanical luminosity of the stellar wind (i.e. energy input rate to the wind bubble) is L_w = 3.6 × 10³⁶ erg s⁻¹ (seen as the black line in both plots).
