Pushing the envelope of exoplanet evolution modelling
, 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

The Astrophysical Journal LettersThe ubiquity of “peas-in-a-pod” architectural patterns and the existence of the radius valley each presents a striking population-level trend for planets with R _p ≤ 4 R _⊕ that serves to place powerful constraints on the formation and evolution of these

Coupled Planetary Interior and Tidal Evolution
The Astrophysical JournalWe present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...

Unexpected Near-Resonant and Metastable States of Young Multiplanet Systems
The Astrophysical JournalRecent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution.

Main-sequence exoplanet systems: tidal evolution
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 ...

The Astronomical JournalAtmospheric escape’s potential to shape the exoplanet population motivates detailed observations of systems actively undergoing escape. AU Mic is a young and active M dwarf hosting two close-in transiting sub- to Neptune-sized planets. Atmospheric escape

Not All Sub-Neptune Exoplanets Have Magma Oceans
The Astrophysical Journal LettersThe evolution and structure of sub-Neptunes may be strongly influenced by interactions between the outer gaseous envelope of the planet and a surface magma ocean.

UniverseThe distribution of period ratios for 580 known two-planet systems is apparently nonuniform, with several sharp peaks and troughs. In particular, the vicinity of the 2:1 commensurability seems to have a deficit of systems.

Interior and Climate Modeling of the Venus Zone Planet TOI-2285 b
The Astronomical JournalAs the discovery of exoplanets progresses at a rapid pace, the large number of known planets provides a pathway to assess the stellar and planetary properties that govern the climate evolution of terrestrial planets.
