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

The Effects of Irradiation on Hot Jovian Atmospheres: Heat Redistribution and Energy Dissipation

, 2012
Hot Jupiters, due to the proximity to their parent stars, are subjected to a strong irradiating flux which governs their radiative and dynamical properties.

The Role of N2 as a Geo-Biosignature for the Detection and Characterization of Earth-like Habitats [PDF]

, 2019
Since the Archean, N2 has been a major atmospheric constituent in Earth's atmosphere. Nitrogen is an essential element in the building blocks of life, therefore the geobiological nitrogen cycle is a fundamental factor in the long term evolution of both ...

The ARCiS framework for Exoplanet Atmospheres: The Cloud Transport Model [PDF]

, 2019
Understanding of clouds is instrumental in interpreting current and future spectroscopic observations of exoplanets. Modelling clouds consistently is complex, since it involves many facets of chemistry, nucleation theory, condensation physics ...

Fleeting but Not Forgotten: The Imprint of Escaping Hydrogen Atmospheres on Super-Earth Interiors

The Astrophysical Journal
Small, close-in exoplanets are divided into two subpopulations: super-Earths and sub-Neptunes. Most super-Earths are thought to have lost their primordially accreted hydrogen-dominated atmospheres via thermally driven winds.

Constraining Atmospheric Composition from the Outflow: Helium Observations Reveal the Fundamental Properties of Two Planets Straddling the Radius Gap

The Astronomical Journal
TOI-836 is a ∼2–3 Gyr K dwarf with an inner super Earth ( R  = 1.7 R _⊕ , P = 3.8 days) and an outer mini-Neptune ( R  = 2.6 R _⊕ , P = 8.6 days). JWST/NIRSpec 2.8–5.2 μ m transmission spectra are flat for both planets.

The Inhomogeneity Effect. II. Rotational and Orbital States Impact Planetary Cooling

The Astrophysical Journal, 2023
We generalize the theory of the inhomogeneity effect to enable comparison among different inhomogeneous planets. A metric of inhomogeneity based on the cumulative distribution function is applied to investigate the dependence of planetary cooling on ...
