Possible in situ formation of Uranus and Neptune via Pebble Accretion

Claudio Valletta, Ravit Helled

The origin of Uranus and Neptune is still unknown. In particular, it has been challenging for planet formation models to form the planets in their current radial distances within t…

Enrichment of Jupiter's atmosphere by late planetesimal bombardment

Sho Shibata, Ravit Helled

Jupiter's atmosphere is enriched with heavy elements by a factor of about 3 compared to proto-solar. The origin of this enrichment and whether it represent the bulk composition of…

Ariel Planetary Interiors White Paper

Ravit Helled, Stephanie Werner, Caroline Dorn +10

The recently adopted Ariel ESA mission will measure the atmospheric composition of a large number of exoplanets. This information will then be used to better constrain planetary bu…

Connecting gravity field, moment of inertia, and core properties in Jupiter through empirical structure models

Benno A. Neuenschwander, Ravit Helled, Naor Movshovitz +1

Constraining Jupiter's internal structure is crucial for understanding its formation and evolution history. Recent interior models of Jupiter that fit Juno's measured gravitational…

Formation of intermediate-mass planets via magnetically-controlled disk fragmentation

Hongping Deng, Lucio Mayer, Ravit Helled

Intermediate mass planets, from Super-Earth to Neptune-sized bodies, are the most common type of planets in the galaxy. The prevailing theory of planet formation, core-accretion, p…

Theoretical vs. observational uncertainties: composition of giant exoplanets

Simon Müller, Maya Ben-Yami, Ravit Helled

In order to characterize giant exoplanets and better understand their origin, knowledge of how the planet's composition depends on its mass and stellar environment is required. In…
