JWST Transmission Spectroscopy of TOI-3235 b: Challenges in Constraining Giant Planet Atmospheres Around M Dwarfs Amid Stellar Contamination

Zoe Ko, Néstor Espinoza, Andrés Jordán +7

Giant planets orbiting low-mass M dwarfs challenge current planet formation theories, which predict that such planets are unlikely to form. Characterizing their atmospheres can pro…

The New Generation Planetary Population Synthesis (NGPPS) VIII. Impact of host star metallicity on planet occurrence rates, orbital periods, eccentricities, and radius valley morphology

Di-Chang Chen, Christoph Mordasini, Alexandre Emsenhuber +3

The dust-to-gas ratio in the protoplanetary disk, which is likely imprinted into the host star metallicity, is a property that plays a crucial role during planet formation. We aim…

Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets

David Trevascus, Sarah Blunt, Valentin Christiaens +22

Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…

Water-rich sub-Neptunes and rocky super Earths around different Stars: Radii shaped by Volatile Partitioning, Formation, and Evolution

Remo Burn, Komal Bali, Caroline Dorn +2

The nature of sub-Neptunes remains unknown due to degeneracies in interior structure solutions. However, a statistical set of small planets with measured masses and radii can be us…

Resonant sub-Neptunes are puffier

Adrien Leleu, Jean-Baptiste Delisle, Remo Burn +12

A systematic, population-level discrepancy exists between the densities of exoplanets whose masses have been measured with transit timing variations (TTVs) versus those measured wi…

A radius valley between migrated steam worlds and evaporated rocky cores

Remo Burn, Christoph Mordasini, Lokesh Mishra +4

The radius valley (or gap) in the observed distribution of exoplanet radii, which separates smaller super-Earths from larger sub-Neptunes, is a key feature that theoretical models…

Planetary system architectures with low-mass inner planets: Direct imaging exploration of mature systems beyond 1 au

Celia Desgrange, Julien Milli, Gael Chauvin +20

The discovery of planets orbiting at less than 1 au from their host star and less massive than Saturn in various exoplanetary systems revolutionized our theories of planetary forma…
