Image Details
Caption: Figure 6.
Luminosity–color tracks, shown with gray symbols, for unresolved binaries composed of an M dwarf with [Fe/H] = −1.5 and an H WD. Analogous tracks for binaries composed of an M dwarf with [Fe/H] = 0 and either an H or He WD look very similar though not identical. Data, shown as colored symbols, are the same as in Figure 1 and in the middle panel in Figure 2.
