Tempawral: A Time-Resolved Retrieval Framework for Variable Brown Dwarfs and Exoplanets
Fei Wang, Ben Burningham, Stuart Littlefair +4
Brown dwarfs and exoplanets are thought to host complex atmospheric phenomena such as clouds, storms, and chemical heterogeneity, akin to weather patterns on Earth. These features…

On the use of polarized thermal emission to constrain cloud grain size and temperature structure of sub-stellar objects
Fei Wang, Yuka Fujii, Ben Burningham +1
Emission spectroscopy is an invaluable tool for probing the atmospheres of brown dwarfs and exoplanets, but interpretations based on flux spectra alone often suffer from degeneraci…
