Retrieved volume mixing ratios for H2O (top row) and OH (bottom row), performed with the high-resolution data only (left column), low-resolution data only (middle column), and combined datasets (right column). We show the constraints for the dissociation model in blue (for the deep atmosphere/undissociated abundance), and the H2O-dissociation model in red. We also show the median value and ±1𝜎 constraint for the cases where a species was detected, and 2𝜎 upper limits where no clear detection was obtained. The retrieved values and detection significances for each species are given in Table 2. -- astro-ph.E

Revealing H2O Dissociation In WASP-76~b Through Combined High- and Low-resolution Transmission Spectroscopy

by Keith CowingMay 6, 2024

Numerous chemical constraints have been possible for exoplanetary atmospheres thanks to high-resolution spectroscopy (HRS) from ground-based facilities as well as low-resolution spectroscopy (LRS) from space.
