Secular orbital dynamics of the innermost exoplanet of the $$\upsilon $$-Andromedæ system [PDF]

open access: yesCelestial Mechanics and Dynamical Astronomy, 2023
Abstract We introduce a quasi-periodic restricted Hamiltonian to describe the secular motion of a small-mass planet in a multi-planetary system. In particular, we refer to the motion of $$\upsilon $$

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

open access: yes, 2018
International audienceThe 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 ...

The composition and dynamics of exoplanet atmospheres. [PDF]

open access: yes
The study of exoplanets has rapidly developed in the last twenty years, and the detailed characterization of planetary atmospheres has become a key area of research.\ud \ud For transiting planets around bright stars, atmospheric features can be detected with transmission spectroscopy.

Aerosols in Exoplanet Atmospheres [PDF]

open access: yes, 2021
Observations of exoplanet atmospheres have shown that aerosols, like in the Solar System, are common across a variety of temperatures and planet types. The formation and distribution of these aerosols are inextricably intertwined with the composition and

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.

Exoplanet winds: Modelling atmospheric dynamics via resolved spectral lines [PDF]

open access: yes, 2021
This thesis benchmarked a new probe of atmospheric dynamics in exoplanet atmospheres by resolving the spectral lines stemming from these far atmospheres and then modelling their line shape taking into account the broadening from atmospheric winds.

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain

open access: yesThe Astronomical Journal, 2023
In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...

Workshop Summary: Exoplanet Orbits and Dynamics

open access: yesPublications of the Astronomical Society of the Pacific, 2023
Abstract Exoplanetary systems show a wide variety of architectures, which can be explained by different formation and dynamical evolution processes. Precise orbital monitoring is mandatory to accurately constrain their orbital and dynamical parameters.
