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

Simultaneous characterization of the atmospheres, surfaces, and exomoons of nearby rocky exoplanets

Earth and Planetary Physics, 2018
Atmospheric composition is an important indicator of habitability and life. The presence or absence of a large exomoon around an Earth-size exoplanet could have important consequences for planet climate stability.

Oxygen False Positives on Habitable Zone Planets Around Sun‐Like Stars

AGU Advances, 2021
Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen‐rich atmospheres without life.

Aerosols in Exoplanet Atmospheres [PDF]

Journal of Geophysical Research: Planets, 2021
AbstractObservations 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 distribution of these aerosols are inextricably intertwined with the composition and thermal structure of the atmosphere.
