Forward-modeling The Uncertainty Budget of High-resolution Spectroscopy of Exoplanet Atmospheres
Ground-based high-resolution cross-correlation spectroscopy (HRCCS; R >~ 15,000) is a powerful complement to space-based studies of exoplanet atmospheres. By resolving individual spectral lines, HRCCS can precisely measure chemical abundance ratios, […]
