Zonal winds of Uranus and Neptune: Gravitational harmonics, dynamic self-gravity, shape, and rotation
Deniz Soyuer, Benno Neuenschwander, Ravit Helled
Uranus and Neptune exhibit fast surface zonal winds that can reach up to few hundred meters per second. Previous studies on zonal gravitational harmonics and Ohmic dissipation cons…
Earth as an Exoplanet. II. Earth's Time-variable Thermal Emission and Its Atmospheric Seasonality of Bioindicators
Jean-Noel Mettler, Sascha P. Quanz, Ravit Helled +2
We assess the dependence of Earth's disk-integrated mid-infrared thermal emission spectrum on observation geometries and investigate which and how spectral features are impacted by…
Potential long-term habitable conditions on planets with primordial H-He atmospheres
Marit Mol Lous, Ravit Helled, Christoph Mordasini
Cold super-Earths which retain their primordial, H-He dominated atmosphere could have surfaces that are warm enough to host liquid water. This would be due to the collision induced…
Jupiter's Temperature Structure: A Reassessment of the Voyager Radio Occultation Measurements
Pranika Gupta, Sushil K. Atreya, Paul G. Steffes +12
The thermal structure of planetary atmospheres is an essential input for predicting and retrieving the distribution of gases and aerosols, as well as the bulk chemical abundances.…
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…
