Component spectral type distributions for a simulated sample of VLM dwarf binaries assuming a uniform age distribution over 0.5–8 Gyr, a power-law mass distribution ﹩\frac{dN}{dM}\propto {M}^{-0.6}﹩ for 0.01 M⊙ ≤ M ≤ 0.1 M⊙, a power-law mass ratio distribution ﹩\frac{dN}{dq}\propto {q}^{4}﹩ for 0.2 ≤ q ≤ 1, I. Baraffe et al. (2003) evolutionary models, and the M. J. Pecaut & E. E. Mamajek (2013) spectral type/effective temperature relation. Color shading indicates the relative density distribution for each spectral type combination.
