UGC 7639: A Dwarf Galaxy in the Canes Venatici I Cloud

Figure 7

The rest-frame evolution of (NUV-r) versus color-magnitude diagram from our simulation of UGC 7639. Dotted line shows its evolutionary path; open symbols mark some meaningful evolutionary times in Gyr (see text); (red) triangle shows its current position. The observed position is given by the filled square, accounting for the same distance modulus as in Figure 4, and the corresponding 1σ uncertainty. The red (magenta) and the blue (cyan) sequences are also plotted following the same prescriptions as in Figure 3.
