One model for explaining the distribution of this quantity in the galactic disk assumes the instantaneous recycling approximation and ignores both infall and outflow. The non-existence of objects with low values of this quantity in the Closed-Box model is referred to as the G-Dwarf Problem. Objects with very low values of this quantity can hypothetically undergo runaway pair-production, resulting in core collapse. Hypothetical objects for which this value is zero are called (*) "population III" and were created soon after the Big Bang. It is either symbolized Z or measured as the log base 10 of iron over hydrogen for the object in question minus said calculation for the sun. For 10 points, name this property, the fraction of a star's mass that isn't hydrogen or helium.
