Warm giant exoplanet characterisation: current state, challenges and outlook [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The characterisation of giant exoplanets is crucial to constrain giant planet formation and evolution theory and for putting the solar-system’s giant planets in perspective. Typically, mass-radius (M-R) measurements of moderately irradiated warm Jupiters

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain

open access: yesThe Astronomical Journal, 2023
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±

Patchy Forsterite Clouds in the Atmospheres of Two Highly Variable Exoplanet Analogs [PDF]

open access: yesAstrophysical Journal, 2022
We present an atmospheric retrieval analysis of a pair of highly variable, ∼200 Myr old, early T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J21392676+0220226 using the Brewster retrieval framework.

Importance of Sample Selection in Exoplanet-atmosphere Population Studies [PDF]

open access: yesAstronomical Journal, 2022
Understanding planet formation requires robust population studies, which are designed to reveal trends in planet properties. In this work we aim to determine if and how different methods for selecting populations of exoplanets for atmospheric ...

Lithium abundances in exoplanet host stars as test of planetary formation scenarii [PDF]

open access: greenEAS Publications Series, 2005
Following the observations of Israelian et al. 2004, we compare different evolutionary models in order to study the lithium destruction processes and the planetary formation scenarii.

Exoplanet weather and climate regimes with clouds and thermal ionospheres. A model grid study in support of large-scale observational campaigns [PDF]

open access: yesAstronomy & Astrophysics, 2022
With observational efforts moving from the discovery into the characterisation mode, systematic campaigns that cover large ranges of global stellar and planetary parameters will be needed.

Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass Loss

open access: yesThe 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.
