Retrievals of Cassini/VIMS occultation of Titan. Top left: observations and best-fit TauREx retrievals. Bottom left: breakdown of the extinction contributions in the tholin + CH4(l)(HITRAN) case. Right: Atmospheric properties inferred for the tholin + CH4(l) (HITRAN) case. The source for the opacity data (i.e, HITRAN or ExoMol) is important and can slightly change the best-fit spectrum and retrieval interpretation. Overall, the Cassini data is dominated by molecular absorption from CH4, CO, C2H6, C3H8 and extinction by hydrocarbon aerosols (tholins + CHCH4(l). The shape of the 3.4 µm absorption feature is likely best explained by the contribution of multiple species including some contribution from tholins. Overall, retrieval interpretations of Titan’s atmosphere are compatible with stratospheric inferences from previous works (see Figure B1). -- astro-ph.EP

Cloud and Haze Parameterization in Atmospheric Retrievals: Insights from Titan’s Cassini Data and JWST Observations of Hot Jupiters

by Keith CowingMay 27, 2025May 27, 2025

Context: Before JWST, telescope observations were not sensitive enough to constrain the nature of clouds in exo-atmospheres. Recent observations, however, have inferred cloud signatures as well as haze-enhanced scattering slopes […]

The full 0.6–2.8 µm NIRISS/SOSS spectrum of WASP-96 b from Radica et al. (submitted). The pixel level spectrum is shown in grey, as well as when binned to a resolution of R=500, 250, and 125 in purple, blue, and red respectively. -- astro-ph.EP
