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.

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

ExoMDN: Rapid characterization of exoplanet interior structures with Mixture Density Networks [PDF]
Astronomy & Astrophysics, 2023 Characterizing the interior structure of exoplanets is essential for understanding their diversity, formation, and evolution. As the interior of exoplanets is inaccessible to observations, an inverse problem must be solved, where numerical structure ...

LkCa 15: A YOUNG EXOPLANET CAUGHT AT FORMATION? [PDF]
The Astrophysical Journal, 2011 Young and directly imaged exoplanets offer critical tests of planet-formation models that are not matched by RV surveys of mature stars. These targets have been extremely elusive to date, with no exoplanets younger than 10--20 Myr and only a handful of direct-imaged exoplanets at all ages.

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

The Clear Sky Corridor: Insights Towards Aerosol Formation in Exoplanets Using An AI-based Survey of Exoplanet Atmospheres [PDF]
The Astronomical JournalAbstract Producing optimized and accurate transmission spectra of exoplanets from telescope data has traditionally been a manual and labor intensive procedure. Here we present the results of the first attempt to improve and standardize this procedure by using artificial-intelligence-based (AI-based) processing of light curves and ...

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

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