The sun is mostly hydrogen and helium, but it also has significant traces of heavier elements like oxygen, carbon and iron, a quality astronomers call "metallicity" despite the nonmetallic nature of some of those elements.

The extremely low metallicity of these stars may also play several parts in the final stellar/brown object.

For example, in a planetary system around a star with solar metallicity, do the dynamics of formation lead to rather a lot of ~Earth mass planets+Luna mass moons+Jovian mass gas giants, all nicely spaced goldilocks zone, screening, etc?

Now a part of this estimate, an priori assumption is also used based on the existence of a band in the galaxy with stars that have statistically an optimal metallicity elements higher in atomic number than helium that is about 10% of the galaxy.
