Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations

, 2011
We use three-dimensional simulations to study the atmospheric circulation on the first Earth-sized exoplanet discovered in the habitable zone of an M star.

The Transiting Exoplanet Community Early Release Science Program for JWST [PDF]

Publications of the Astronomical Society of the Pacific, 2018
The James Webb Space Telescope (JWST) presents the opportunity to transform our understanding of planets and the origins of life by revealing the atmospheric compositions, structures, and dynamics of transiting exoplanets in unprecedented detail. However,

Vertical structure of an exoplanet’s atmospheric jet stream [PDF]

Nature
Ultra-hot Jupiters, an extreme class of planets not found in our Solar System, provide a unique window into atmospheric processes. The extreme temperature contrasts between their day and night sides pose a fundamental climate puzzle: how is energy ...

Analytical model for starshade formation flying with applications to exoplanet direct imaging observation scheduling

, 2021
We present an analytical model for the desired kinematics of the starshade-telescope relative motion during exoplanet direct imaging observations. We combine this model with an existing deadbanding strategy published by the NASA JPL S5 Team to define a ...

Classification of Trajectories in a Two-planet Exosystem Using the Generalized Three-body Problem

The Astrophysical Journal, 2023
We deploy the theory of the generalized three-body problem to describe an exosystem composed of a host star, a transiting Jupiter-sized exoplanet, and an Earth-sized exoplanet.

The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet β Pictoris b from Combined Direct Imaging and Astrometry [PDF]

The Astronomical Journal, 2020
Abstract We present new observations of the planet β Pictoris b from 2018 with the Gemini Planet Imager (GPI), the first GPI observations following conjunction. Based on these new measurements, we perform a joint orbit fit to the available relative astrometry from ground-based imaging, the Hipparcos Intermediate Astrometric Data (IAD ...

VIBES: Visual Binary Exoplanet survey with SPHERE [PDF]

, 2020
Recent surveys indicate that planets in binary systems are more abundant than previously thought, which is in agreement with theoretical work on disc dynamics and planet formation in binaries.

Atmospheres on Nonsynchronized Eccentric-tilted Exoplanets. I. Dynamical Regimes [PDF]

The Astrophysical Journal, 2019
Abstract Relatively long-period, nonsynchronized planets—such as warm Jupiters—potentially retain the primordial rotation, eccentricity, and obliquity that might encapsulate information on planetary climate and formation processes. To date, there has not been a systematic study on climate patterns on these planets that will significantly
