JWST-TST DREAMS: Nonuniform Dayside Emission for WASP-17b from MIRI/LRS

The Astronomical Journal
We present the first spectroscopic characterization of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation.

Chemical modeling of exoplanet atmospheres

, 2014
International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

Bistability, Oscillations, and Multistability on Hycean Planets

The Astrophysical Journal
Hycean planets are hypothetical exoplanets characterized by H _2 O oceans and H _2 -rich atmospheres. These planets are high-priority targets for biosignature searches, as they combine abundant surface liquid water with easy-to-characterize H _2 -rich ...

Individual and Statistical Characterization of the Giant Exoplanet Population

, 2021
The field of observational exoplanet astronomy has seen tremendous progress over the span of only a few decades. Now, we find ourselves at the dawn of a new era: the characterization of distant worlds.

The Spin Zone: Synchronously and Asynchronously Rotating Land Planets Have Spectral Differences in Transmission

The Planetary Science Journal
New observational facilities are beginning to enable insights into the three-dimensional (3D) nature of exoplanets. Transmission spectroscopy is the most widely used method for characterizing transiting temperate exoplanet atmospheres, but because it ...

Blowin’ in the Nonisothermal Wind: Core-powered Mass Loss with Hydrodynamic Radiative Transfer

The Astrophysical Journal
The mass loss rates of planets undergoing core-powered escape are usually modeled using an isothermal Parker-type wind at the equilibrium temperature, T _eq .

Spectra as windows into exoplanet atmospheres

, 2014
Understanding a planet’s atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability.

The PHOENIX Exoplanet Retrieval Algorithm and Using H− Opacity as a Probe in Ultrahot Jupiters

, 2020
Atmospheric retrievals are now a standard tool to analyze observations of exoplanet atmospheres. This data-driven approach quantitatively compares atmospheric models to observations in order to estimate atmospheric properties and their uncertainties.

Atmospheric Library of Far Away Worlds: Developing a Library of Model Simulations to Interpret Observations of Exoplanet Atmospheres [PDF]

, 2019
The number of exoplanets that have been discovered now exceeds 3500. This population of exoplanets contains a rich diversity, for example; hot Jupiters, warm Neptunes, super Earths and Earth-like planets, exhibiting variation in the planetary mass ...
