The distribution of heavy-elements in giant protoplanetary atmospheres: the importance of planetesimal-envelope interactions
Claudio Valletta, Ravit Helled
In the standard model for giant planet formation, the planetary growth begins with accretion of solids followed by a buildup of a gaseous atmosphere as more solids are accreted, an…
A Quantitative Comparison of Exoplanet Catalogs
Dolev Bashi, Ravit Helled, Shay Zucker
In this study, we investigated the differences between four commonly-used exoplanet catalogs (exoplanet.eu; exoplanetarchive.ipac.caltech.edu; openexoplanetcatalogue.com; exoplanet…
Forming Mercury by Giant Impacts
Alice Chau, Christian Reinhardt, Ravit Helled +1
The origin of Mercury's high iron-to-rock ratio is still unknown. In this work we investigate Mercury's formation via giant impacts and consider the possibilities of a single giant…
On the diversity in mass and orbital radius of giant planets formed via disk instability
Simon Müller, Ravit Helled, Lucio Mayer
We present a semi-analytical population synthesis model of protoplanetary clumps formed by disk instability at radial distances of 80 - 120 AU. Various clump density profiles, init…
