Characterization of exoplanets from their formation [PDF]
A first characterization of many exoplanets has recently been achieved by the observational determination of their radius. For some planets, a measurement of the luminosity has also been possible, with many more directly imaged planets expected in the future.

Exoplanet Volatile Carbon Content as a Natural Pathway for Haze Formation
We explore terrestrial planet formation with a focus on the supply of solid-state organics as the main source of volatile carbon. For the water-poor Earth, the water ice line, or ice sublimation front, within the planet-forming disk has long been a key ...

The Roman Microlensing Survey: Confirmation or Refutation of Gas Giant Exoplanet Formation Theories
Exoplanet research has moved from the discovery of new classes of planets toward creating a census of exoplanet population demographics across the spectrum of exoplanet and host star masses.

Let’s Sweep: The Effect of Evolving J 2 on the Resonant Structure of a Three-planet System
Short and ultrashort period planets are peculiar types of exoplanets with periods as short as a few days or less. Although it is challenging to detect them, already several have been observed, with many additional candidates.

We investigate and compare the composition of M-dwarf planets in systems with only one known planet (“singles”) to those residing in multiplanet systems (“multis”) and the fundamental properties of their host stars.

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

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

The ARCiS framework for Exoplanet Atmospheres: The Cloud Transport Model [PDF]
Understanding of clouds is instrumental in interpreting current and future spectroscopic observations of exoplanets. Modelling clouds consistently is complex, since it involves many facets of chemistry, nucleation theory, condensation physics ...

Exoplanet albedo spectra and colors as a function of planet phase, separation, and metallicity [PDF]
First generation optical coronagraphic telescopes will obtain images of cool gas and ice giant exoplanets around nearby stars. The albedo spectra of exoplanets at planet-star separations larger than about 1 AU are dominated by reflected light to beyond 1
