True Polar Wander of Lava Worlds
The Astrophysical Journal Letters, 2023 As one of the most detectable types of terrestrial planets, lava worlds are highly prioritized targets for exoplanet atmosphere characterization since their atmospheres may reveal what they are made of and how.

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.

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System
The Astronomical Journal, 2023 The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

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.

Evolution of Planetary Obliquity: The Eccentric Kozai–Lidov Mechanism Coupled with Tide
The Astrophysical Journal, 2023 Planetary obliquity plays a significant role in determining the physical properties of planetary surfaces and climate. As direct detection is constrained due to the present observation accuracy, kinetic theories are helpful for predicting the evolution ...

Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass Loss
The Astronomical Journal, 2023 A gap in exoplanets’ radius distribution has been widely attributed to the photoevaporation threshold of their progenitors’ gaseous envelope. Giant impacts can also lead to substantial mass loss.

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.

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 ...
