The Compositional and Dynamical Properties of Exoplanets
The solid surface density profile of protoplanetary discs, and the composition of these solids, can be formed through sequential condensation models of dust precipitating from the cooling gas of the solar nebula. I continue developing a code that reproduces the chemical compositions of most chondrites as well as the bulk compositions of the rocky ...openaire +1 more source
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

Discovery, Characterization, and Dynamics of Transiting Exoplanets [PDF]
, 2015 Are we alone in the Universe? So far, the question remains unanswered, but a significant leap forward was achieved two decades ago, with the discovery of the first planets orbiting stars other than our Sun. Almost 2000 exoplanets have now been detected.

Interior dynamics of small-core and coreless exoplanets
Since the first exoplanet detection in 1992, the study of exoplanets has received considerable attention. It is becoming apparent that the diversity of the general exoplanet population extends beyond that of the Solar System and includes a variety of structures and compositions.Caroline Hasler, Paul Tackley

The long-term tidal dynamics of differentiated rocky exoplanets
OverviewTidal interaction plays a unique role in coupling the thermal, orbital, and rotational evolution of close-in moons and exoplanets. The reaction of a planetary body subjected to tidal loading is determined by its interior structure, rheological properties, and orbital parameters. The interior and orbital dynamics are, conversely, affected by theMichaela Walterova, Marie Behounkova

Connecting exoplanet mantle mineralogy to surface dynamic regime
Based on stellar compositions, we know that rocky exoplanets show a diversity in interior compositions, and therefore mantle mineralogies. The mantle mineralogy controls physical parameters of the mantle, such as viscosity, and therefore strongly affects thermal and dynamical evolution of the interior.Rob Spaargaren +3 more
