Transiting Exoplanet Atmospheres in the Era of JWST
Reviews in Mineralogy & GeochemistryThe field of exoplanet atmospheric characterization has recently made considerable advances with the advent of high-resolution spectroscopy from large ground-based telescopes and the commissioning of the James Webb Space Telescope (JWST). We have entered

The Orbital Geometries and Stellar Obliquities of Exoplanet-hosting Multistar Systems
Astronomical JournalThe current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multistar systems, which may have their evolution ...

Pushing the envelope of exoplanet evolution modelling [PDF]
, 2021 Propelled by the discovery of the first exoplanet thirty years ago, the scientific community has rallied and made tremendous strides towards a full understand of the formation and evolution of planetary systems. During this period, over 4, 300 confirmed exoplanets have been detected, and the resulting dataset has driven a revolution by allowing for new

Evolution of Angular Momentum Distribution in Exoplanet Systems
Astrophysics, 2015The distribution of angular momentum is investigated in “star–planet systems, taking due account of stellar evolution effects. Numerical simulation is carried out for 15 systems for which stellar rotation data are available. Consideration of changes in stellar structure is confirmed to be significant for the evolution of momentum distribution.

Tidal evolution of close-in exoplanets
2014The continuous action of tides modify the rotation of close-in planets together with its orbit until an equilibrium situation is reached. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous rotation is observed for the majority of the satellites in the solar system. However, in the

The Irradiation-Driven Evolution of Gas-Giant Exoplanets
2022Nearly thirty years after their initial discovery, we now know of over five thousand extrasolar planets. Intensive efforts have been made to characterize the sizes, masses, orbits, and compositions of these new worlds, and the resulting population challenges our intuition from the Solar System.

The time evolution of the ultraviolet habitable zone
For stars hosting Circumstellar Habitable Zone (CHZ) exoplanets, we investigate the time-evolution of their ultraviolet habitable zone (UHZ), the annular region around a star where an exoplanet could experience a suitable ultraviolet environment for the ...

Coupling the Atmospheric and Dynamical Evolution of Close-in Exoplanets
The vast majority of the detected exoplanets orbit in less than a month around their star, in extreme conditions unmet in the Solar System. The demographics of these close-in planets exhibit a striking feature: the lack of Neptune-size worlds on very short orbits, also dubbed the "Neptunian desert", which challenges our understanding of planetary ...Omar Attia, Vincent Bourrier
