Oxygen is the most abundant "metal" element in stars and in the cosmos. But determining oxygen abundances in stars has proven challenging, because of the shortage of detectable atomic oxygen lines in their optical spectra as well as observational and theoretical complications with these lines (e.g., blends, three-dimensional, non-LTE). Nonetheless, Ting et al. were recently able to demonstrate that oxygen abundances can be determined from low-resolution (R ≃ 2000) optical spectra. Here, we...[Show more]
