Beyond Pebble Isolation: Diverse Pathways to Giant Planet Formation Across Stellar and Orbital Scales
Lorenzo Peerani, Sho Shibata, Ravit Helled
Context. Giant planet formation requires reaching crossover mass, i.e., when the mass of the gaseous envelope becomes equal to the mass of the core, within the disc's lifetime. The…

The metallicity of giant exoplanets around low-mass stars and how Ariel can help
Ravit Helled, Sho Shibata, Shubham Kanodia +1
Giant planets orbiting low-mass stars represent a unique population of giant planets that can be studied to constrain planet formation theory. Surveys of transiting giant exoplanet…

Elevated Eccentricities in the Radius Valley Hint at Water-Rich Mini-Neptunes
Sho Shibata, Andre Izidoro
While recent planet-formation models broadly reproduce the observed population of super-Earths and mini-Neptunes, as well as the bimodal radius distribution (the ``radius valley'')…
