WASP-80 b, a warm sub-Jovian (equilibrium temperature ~820 K, 0.5 Jupiter masses), presents an opportunity to characterize a rare gas giant exoplanet around a low-mass star.
WASP-80 b
![Haze (tholin and soot) models from Jacobs et al. (2023) for two metallicities: [M/H] = 0 (solid) and [M/H] = 1 (dashed). The various formation rates are shown in cool colors for the tholins and in warm colors for the soots. The haze models are compared to the NIRISS/SOSS eclipse spectrum of WASP-80 b. If the aerosols are hazes, they could consist of soots or tholins, with formation rates for tholins most likely lower than 10−11.5g cm−2 s−1. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/03/A-Moderate-Albedo-From-Reflecting-Aerosols.png?resize=1200%2C719&ssl=1)

A Moderate Albedo From Reflecting Aerosols On The Dayside Of WASP-80 b Revealed By JWST/NIRISS Eclipse Spectroscopy
Secondary eclipse observations of exoplanets at near-infrared wavelengths enable the detection of thermal emission and reflected stellar light, providing insights into the thermal structure and aerosol composition of their atmospheres.

Methane And Water Found In The Atmosphere Of Exoplanet WASP-80 b
NASA’s James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas […]
