Lightning and charge processes in brown dwarf and exoplanet atmospheres. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 The study of the composition of brown dwarf atmospheres helped to understand their formation and evolution. Similarly, the study of exoplanet atmospheres is expected to constrain their formation and evolutionary states.

Observations of Exoplanet Atmospheres [PDF]
Publications of the Astronomical Society of the Pacific, 2015 Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and disequilibrium processes.

Aggregate Hazes in Exoplanet Atmospheres [PDF]
The Astrophysical Journal, 2019 Abstract Photochemical hazes have frequently been used to interpret exoplanet transmission spectra that show an upward slope toward shorter wavelengths and weak molecular features. While previous studies have only considered spherical haze particles, photochemical hazes composed of hydrocarbon aggregate particles are common throughout ...

Highlights in the Study of Exoplanet Atmospheres [PDF]
Nature, 513, pp. 345-352, 2014, 2014 Exoplanets are now being discovered in profusion. However, to understand their character requires spectral models and data. These elements of remote sensing can yield temperatures, compositions, and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are achieved.

Understanding Exoplanet Atmospheres with UV Observations I: NUV and Blue/Optical [PDF]
arXiv, 2019 Much of the focus of exoplanet atmosphere analysis in the coming decade will be atinfrared wavelengths, with the planned launches of the James Webb Space Telescope (JWST) and the Wide-Field Infrared Survey Telescope (WFIRST). However, without being placed in the context of broader wavelength coverage, especially in the optical and ultraviolet, infrared

A New Method For Studying Exoplanet Atmospheres Using Planetary Infrared Excess [PDF]
ApJL 898 L35 (2020), 2020 To date, the ability for observers to reveal the composition or thermal structure of an exoplanet's atmosphere has rested on two techniques: high-contrast direct imaging and time-series observations of transiting exoplanets. The former is currently limited to characterizing young, massive objects while the latter requires near 90 degree orbital ...

Exoplanet Atmosphere Measurements from Transmission Spectroscopy and other Planet-Star Combined Light Observations [PDF]
, 2017 It is possible to learn a great deal about exoplanet atmospheres even when we cannot spatially resolve the planets from their host stars. In this chapter, we overview the basic techniques used to characterize transiting exoplanets - transmission spectroscopy, emission and reflection spectroscopy, and full-orbit phase curve observations.
