Face-on stellar surface density profiles in terms of R/R_*, 50 where R_*, 50 is the stellar half-mass radius, for a galaxy with a bar in the TNG50-like model (top) and unbarred galaxy in the strong wind model (bottom) at z = 0, 1. The profiles (black lines) were obtained by fitting simultaneously a Sersic profile for a bulge (red lines) and a Sersic for a bar (pink lines), and an exponential profile (blue lines). Purple lines represent the surface density profile from the predicted Sersic profile and exponential profile. Horizontal dashed lines correspond to the radius at which the fit is done. Dotted horizontal lines correspond to the bar length (pink), the effective radius of the bulge (red), and the scale length of the disc(blue).
