G-Dwarf Problem

(lack of metal-poor G dwarfs in the Milky Way)

The G-Dwarf Problem is that fewer G-Type Stars with low Metallicity are observed in the Milky Way than theories of Galaxy formation and evolution imply there would be. G-class stars have a sufficiently long Main-Sequence lifetime that early-generation examples with low metallicity should still be present.

Some observations of other galaxies suggest the problem is also present regarding them.
