Impact of photochemical hazes and gases on exoplanet atmospheric thermal structure [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We investigate the impact of photochemical hazes and disequilibrium gases on the thermal structure of hot Jupiters, using a detailed 1D radiative-convective model. We find that the inclusion of photochemical hazes results in major heating of the upper and cooling of the lower atmosphere.

Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) [PDF]
Astronomy & Astrophysics, 2020 Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present the analysis of new optical spectroscopy for the transiting ultra-hot Jupiter WASP-121b.

TEMPERATURE STRUCTURE AND ATMOSPHERIC CIRCULATION OF DRY TIDALLY LOCKED ROCKY EXOPLANETS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Next-generation space telescopes will observe the atmospheres of rocky planets orbiting nearby M-dwarfs. Understanding these observations will require well-developed theory in addition to numerical simulations. Here we present theoretical models for the temperature structure and atmospheric circulation of dry, tidally locked ...

Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy [PDF]
Science, 2014 Exoplanets that orbit close to their host stars are much more highly irradiated than their solar system counterparts. Understanding the thermal structures and appearances of these planets requires investigating how their atmospheres respond to such extreme stellar forcing.

Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACTUsing 3D radiative MHD simulations and Lyman-α transit calculations, we investigate the effect of magnetic fields on the observational signatures of atmospheric escape in exoplanets. Using the same stellar wind, we vary the planet’s dipole field strength (Bp) from 0 to 10G.

Rocky Planet or Water World? Observability of Low-density Lava World Atmospheres
The Astrophysical Journal, 2023 Super-Earths span a wide range of bulk densities, indicating a diversity in interior conditions beyond that seen in the solar system. In particular, an emerging population of low-density super-Earths may be explained by volatile-rich interiors.

Exoplanet albedo spectra and colors as a function of planet phase, separation, and metallicity [PDF]
, 2010 First generation optical coronagraphic telescopes will obtain images of cool gas and ice giant exoplanets around nearby stars. The albedo spectra of exoplanets at planet-star separations larger than about 1 AU are dominated by reflected light to beyond 1
