A Possible Metal-dominated Atmosphere below the Thick Aerosols of GJ 1214 b Suggested by Its JWST Panchromatic Transmission Spectrum

The Astrophysical Journal Letters
GJ 1214b is the archetype sub-Neptune for which thick aerosols have prevented us from constraining its atmospheric properties for over a decade. In this study, we leverage the panchromatic transmission spectrum of GJ 1214b established by the Hubble Space

Formation of Super-Earths and Mini-Neptunes from Rings of Planetesimals

The Astrophysical Journal Letters
The solar system's planetary architecture has been proposed to be consistent with the terrestrial and giant planets forming from material rings at ∼1 au and ∼5 au, respectively.

Hundreds of TESS Exoplanets Might Be Larger than We Thought

The Astrophysical Journal Letters
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from the fraction of starlight blocked when a planet transits its host star.

Atmospheric Studies of brown-Dwarfs and Exoplanets: Insights into Planet Formation and Evolution

, 2018
Cette thèse se focalise sur les propriétés atmosphériques des exoplanètes et des naines brunes et le lien avec les mécanismes de formation. Dans la première partie, le ratio des abondances de carbone et d'oxygène (C/O) du compagnon et de son étoile hôte est utilisé comme proxy.

Repelling Planet Pairs by Ping-pong Scattering

The Astrophysical Journal
The Kepler mission reveals a peculiar trough-peak feature in the orbital spacing of close-in planets near mean-motion resonances: a deficit and an excess that are, respectively, a couple of percent interior to and wide of the resonances. This feature has
