CRIRES+ data: CCFo map for night 3, channel B, using the H2O template. The horizontal white lines represent the orbital phases of the HD 209458 b’s expected transit ingress (bottom) and egress (top). The slanted line represent HD 209458 b’s expected radial velocities, corrected from the barycentric velocities, with Vrest = 0 km·s −1 . Rest velocities lower than −25 km·s −1 and larger than +35 km·s −1 are not shown for clarity. -- astro-ph.EP

Four HD 209458 b Transits Through CRIRES+: Detection of H2O and Non-detections of C2H2, CH4, and HCN

by Keith CowingAugust 28, 2024August 27, 2024

HD 209458 b is one of the most studied exoplanets to date. Despite this, atmospheric characterisation studies yielded inconsistent species detections and abundances. Values reported for the C/O ratio range […]
