Could Uranus and Neptune form by collisions of planetary embryos?
Alice Chau, Christian Reinhardt, André Izidoro +2
The origin of Uranus and Neptune remains a challenge for planet formation models. A potential explanation is that the planets formed from a population of a few planetary embryos wi…
Bifurcation in the history of Uranus and Neptune: the role of giant impacts
Christian Reinhardt, Alice Chau, Joachim Stadel +1
Despite many similarities, there are significant observed differences between Uranus and Neptune: while Uranus is tilted and has a regular set of satellites, suggesting their accre…
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…
K2-106, a system containing a metal-rich planet and a planet of lower density
E. W. Guenther, O. Barragan, F. Dai +42
Planets in the mass range from 2 to 15 MEarth are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities,…
