It means the amount of elements that are heavier than hydrogen and helium. Note: The use of spectroscopy provides metallicities for very large stellar samples (34, 35), while the use of surveys reveals the chemistry It remains unproven that disequilibrium chemistry or condensation will always return a conversion factor of unity.
