Synthetic spectra and MCMC analysis establish deuterium detection limits in early-type stars as a function of SNR, Teff, and v sin i, with upper limits D/H < -5.5 dex for HD 32115 and < -4.9 dex for 21 Peg.

Revealing {\alpha}-Element's Past with Subaru/IRD: Oxygen Abundance of 35 Very Metal-Poor Stars from Near-IR OH lines
New NIR OH-based oxygen abundances for 35 VMP stars are empirically calibrated against the [OI] line to flatten the [O/Fe] vs [Fe/H] trend and improve agreement with Galactic chemical evolution models.

Detectability of deuterium in spectra of early-type stars
Synthetic spectra and MCMC analysis establish deuterium detection limits in early-type stars as a function of SNR, Teff, and v sin i, with upper limits D/H < -5.5 dex for HD 32115 and < -4.9 dex for 21 Peg.
