Groundbased and spacecraft telescopic observations, combined with an intensive modeling
effort, have greatly enhanced our understanding of hot giant planets and brown dwarfs over …

The atmosphere of a brown dwarf or extrasolar giant planet controls the spectrum of
radiation emitted by the object and regulates its cooling over time. Although the study of …

We present the easy-to-use, publicly available, Python package petitRADTRANS, built for
the spectral characterization of exoplanet atmospheres. The code is fast, accurate, and …

This paper presents an overview of SPIRou, the new-generation near-infrared
spectropolarimeter/precision velocimeter recently installed on the 3.6-m Canada–France …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The spin of a planet arises from the accretion of angular momentum during its formation,,,
but the details of this process are still unclear. In the Solar System, the equatorial rotation …

Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of
hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

We model the impact of nonuniform cloud cover on transit transmission spectra. Patchy
clouds exist in nearly every solar system atmosphere, brown dwarfs, and transiting …

We present results from the Weather on Other Worlds Spitzer Exploration Science program
to investigate photometric variability in L and T dwarfs, usually attributed to patchy clouds …
