  The growing database of exoplanets have shown us the statistical
characteristics of various exoplanet populations, providing insight towards
their origins. Observational evidence suggests that the process by which gas
giants are conceived in the stellar disk may be disparate from that of smaller
planets. Using NASA's Exoplanet Archive, we analyzed a correlation between the
planet mass and stellar metallicity of low-mass exoplanets (MP < 0.13 MJ)
orbiting spectral class G, K, and M stars. The correlation suggests an
exponential law relationship between the two that is not fully explained by
observation biases alone.
