Abstract

The elements found in second-generation stars probe the nature and end states of the elusive generation of metal-free first stars. High-resolution (R ~ 30,000) ultraviolet (~1800-3100 Å) spectroscopy offers the potential to greatly expand the chemical inventory in second-generation stars. Facilities like CETUS, HabEx, and LUVOIR meet these goals.
