Chemical and Photometric Evolution Models for Disk, Irregular, and Low Mass Galaxies

Figure 8

(a) Radial distributions of the surface density of diffuse gas, Σ_HI, molecular gas, Σ_H2, and stellar mass, Σ_∗, in M_⊙pc⁻², and the star formation rate surface density, Σ_SFR, in M_⊙yr⁻¹pc⁻², all in logarithmic scale, for the least massive galaxy of our example table, with 𝑉_max=48kms⁻¹. (b) Evolution with redshift of radial distributions of elemental abundances, C, N, O, and Fe of the same galaxy.
