(a) Cross-correlation function (CCF) of the WASP39b transmission spectrum with the 12C 16O (98.7%) + 13C 16O (1.3%) template. We compare the CCFs resulting from the self cross-correlation of the template (light blue area) and the spectrum (dark blue area), which were scaled arbitrarily. (b) Distribution of the best-fit Gaussian parameters (significance of the central peak, Speak, the central peak velocity, RVpeak, and the FWHM of the distribution of velocities, σRVs) retrieved from the sampled transmission spectra that were randomly generated following a Gaussian distribution centered in the observed transmission spectrum and considering the errors as the Gaussian standard deviation in each point. We performed 30000 iterations. -- astro-ph.EP

Detection of Carbon Monoxide in the Atmosphere of WASP-39b Applying Standard Cross-Correlation Techniques to JWST NIRSpec G395H Data

by Keith CowingSeptember 6, 2023September 6, 2023

Carbon monoxide was recently reported in the atmosphere of the hot Jupiter WASP-39b using the NIRSpec PRISM transit observation of this planet, collected as part of the JWST Transiting Exoplanet […]
