A survey of exoplanet phase curves with Ariel [PDF]

open access: yes, 2021
The ESA-Ariel mission will include a tier dedicated to exoplanet phase curves corresponding to ∼10% of the science time. We present here the current observing strategy for studying exoplanet phase curves with Ariel.

A Radiative-convective Model for Terrestrial Planets with Self-consistent Patchy Clouds

open access: yesThe Planetary Science Journal, 2023
Clouds are ubiquitous: they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet observations.

Exoplanet Atmospheric Studies At High Spectral Resolution

open access: yes, 2020
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. When a planet pass between its host star and an observer, a fraction of the star-light is absorbed by its atmosphere, thus revealing its

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]

open access: yes, 2014
The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

Characterizing the Atmospheric Dynamics of HD 209458b-like Hot Jupiters Using AI-driven Image Recognition/Categorization

open access: yesThe Astrophysical Journal, 2023
In order to understand the results of recent observations of exoplanets, models have become increasingly complex. Unfortunately, this increases both the computational cost and output size of said models.

Earth as a Transiting Exoplanet: A Validation of Transmission Spectroscopy and Atmospheric Retrieval Methodologies for Terrestrial Exoplanets [PDF]

open access: yes, 2023
The James Webb Space Telescope (JWST) will enable the search for and characterization of terrestrial exoplanet atmospheres in the habitable zone via transmission spectroscopy.

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...

Nitrogen as a Tracer of Giant Planet Formation. I. A Universal Deep Adiabatic Profile and Semianalytical Predictions of Disequilibrium Ammonia Abundances in Warm Exoplanetary Atmospheres

open access: yesThe Astrophysical Journal, 2023
A major motivation of spectroscopic observations of giant exoplanets is to unveil planet formation processes from atmospheric compositions. Several recent studies suggested that atmospheric nitrogen, like carbon and oxygen, can provide important ...

Atmospheric C/O Ratios of Sub-Neptunes with Magma Oceans: Homemade rather than Inherited

open access: yesThe Astrophysical Journal Letters
Recently, the James Webb Space Telescope has enabled detailed spectroscopic characterization of sub-Neptune atmospheres. With detections of carbon- and oxygen-bearing species such as CO, CO _2 , CH _4 , and H _2 O, a central question is whether the ...
