Star Formation Histories of Dwarf Galaxies from the Colour-Magnitude Diagrams of Their Resolved Stellar Populations
Figure 3
Fractional age distributions of stars generated with a constant SFR (0–13 Gyr) for four different completeness limits. In different colours (solid lines) are plotted the contributions from different mass ranges. In (a), only stars with absolute magnitude brighter than 2.5 are plotted, while in (b), (c), and (d), this limit is, respectively, , and . The dotted lines represent the contribution of PMS, MS, SGB. In each panel, the left and right subfigures show, respectively, the adopted simulated population (with the limiting magnitude marked by a red line) and a blow-up with the contribution of intermediate and massive stars in the last 300 Myr.
