The need for laboratory work to aid in the understanding of exoplanetary atmospheres

, 2016
Advancements in our understanding of exoplanetary atmospheres, from massive gas giants down to rocky worlds, depend on the constructive challenges between observations and models.

Glowing giants:Unravelling extreme close-in exoplanet climates [PDF]

The interpretation of general trends in exoplanet atmospheres is challenging because they exhibit a wide range of diverse properties in terms of composition, structure, and overall atmospheric physics.

Photochemical Hazes in Exoplanetary Skies with Diamonds: Microphysical Modeling of Haze Composition Evolution via Chemical Vapor Deposition

The Astrophysical Journal
Observational efforts in the last decade suggest the prevalence of photochemical hazes in exoplanetary atmospheres. Recent JWST observations raise growing evidence that exoplanetary hazes tend to have reflective compositions, unlike the conventionally ...

3D Modeling of Moist Convective Inhibition in Idealized Sub-Neptune Atmospheres

The Astrophysical Journal
Atmospheric convection behaves differently in hydrogen-rich atmospheres compared to higher mean molecular weight atmospheres due to compositional gradients of tracers.

sunset: A database of synthetic atmospheric-escape transmission spectra for nearly every transiting exoplanet

This repository contains the sunset database of atmospheric-escape transmission spectra for most currently known transiting exoplanets. This database is described in Linssen et al. (in review). The complete zipped (unzipped) database is ~5GB (~28GB).

Spectroscopy of Exoplanet Atmospheres with the FINESSE Explorer

, 2012
FINESSE (Fast INfrared Exoplanet Spectroscopic Survey Explorer) will provide uniquely detailed information on the growing number of newly discovered planets by characterizing their atmospheric composition and temperature structure.

Sub-Neptune Memories. I. Implications of Inefficient Mantle Cooling and Silicate Rain

The Astrophysical Journal
We explore the evolution of sub-Neptune (radii between ∼1.5 and 4 R _⊕ ) exoplanet interior structures using our upgraded evolution code, APPLE , which self-consistently couples the thermal and compositional evolution of the whole structure.

PEPSI Investigation, Retrieval, and Atlas of Numerous Giant Atmospheres (PIRANGA). I. The Ubiquity of Fe i Emission and Inversions in Ultrahot Jupiter Atmospheres

The Astronomical Journal
We present high-resolution optical emission spectroscopy observations of the ultrahot Jupiters (UHJs) TOI-1431 b and TOI-1518 b using the PEPSI spectrograph on the LBT.

Exoplanet atmospheres at high spectral resolution

The spectrum of an exoplanet reveals the physical, chemical, and biological processes that have shaped its history and govern its future. However, observations of exoplanet spectra are complicated by the overwhelming glare of their host stars.

Coupled Planetary Interior and Tidal Evolution

The Astrophysical Journal
We present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...
