Long-term evolution of exoplanet systems [PDF]
Proceedings of the International Astronomical Union, 2022 AbstractIn this Review, I discuss recent developments on the long-term dynamical evolution of exoplanet systems, focusing on how distinctive dynamical processes may have shaped the orbital architectures of observed populations. I include three applications that highlight part of my own work. First, I examine the high-eccentricity tidal migration of hot

Thermal and Orbital Evolution of Low-mass Exoplanets [PDF]
The Astrophysical Journal, 2020 Abstract The thermal, orbital, and rotational dynamics of tidally loaded exoplanets are interconnected by intricate feedback. The rheological structure of the planet determines its susceptibility to tidal deformation and, as a consequence, participates in shaping its orbit.

Mapping out the time-evolution of exoplanet processes [PDF]
, 2019 There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make such a characterization increase, we begin to see pathways forward for validating these theories.

Tidal Evolution of Close-in Exoplanets and Host Stars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT The evolution of exoplanetary systems with a close-in planet is ruled by the tides mutually raised on the two bodies and by the magnetic braking of the host star. This paper deals with consequences of this evolution and some features that can be observed in the distribution of the systems' two main periods: the orbital period ...

Evolution of exoplanets and their parent stars [PDF]
EAS Publications Series, 2014 Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type stars.

Effect of Galactic Chemical Evolution on Exoplanet Properties [PDF]
The Astrophysical Journal LettersAbstract We couple a simplified model for galactic chemical evolution with software that models the condensation of dust in protoplanetary disks and software that models the interior structure of planets, in order to estimate the effects that galactic chemical evolution has on the properties of planets as they form over time.

Main-sequence exoplanet systems: tidal evolution [PDF]
The easiest exoplanets to detect are those that orbit very close to their hoststars. As a result, even though these planets are quite rare, they represent amajor fraction of the current exoplanet population. A side-effect of theproximity between the planet and the star is that the two have strong mutualinteractions through a number of physical ...

Exoplanet atmosphere evolution: emulation with neural networks
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Atmospheric mass-loss is known to play a leading role in sculpting the demographics of small, close-in exoplanets. Knowledge of how such planets evolve allows one to ‘rewind the clock’ to infer the conditions in which they formed.
