Consistent gas-phase C/O abundances from UV and optical emission lines: a robust scale for chemical evolution across cosmic time
Paige M. Kelly, Tucker Jones, Yuguang Chen +5
The carbon to oxygen (C/O) abundance ratio is a valuable tracer of star formation history, as C and O enrichment occurs on different timescales. However, measurements based on ultr…
