Abstract

A discussion is conducted on the consequences for star chemical composition studies of the availability of a Very Large Telescope, such as that being planned by the European Southern Observatory. The detailed abundance distribution of the elements, including isotopes, will then be obtainable for a large sample of unevolved, F and G type stars of all ages situated within 2 kpc of the sun, yielding insight into the chemical evolution of the galaxy. The abundances of K-giant stars will also be derivable, allowing a study of the systematic differences in the composition of the central bulge, extended halo, and outer regions of the Galaxy. The light collecting area required for such work is estimated as equivalent to that of a single 12 m-diameter telescope, though it may take the form of two 8.5 m-diameter, or four 6 m-diameter telescopes.
