Carbon from Interstellar Clouds to Habitable Worlds

Edwin A. Bergin, Marc M. Hirschmann, Andre Izidoro

Carbon is an essential element for a habitable world. Inner (r < 3 au) disk planetary carbon compositions are strongly influenced by supply and survival of carbonaceous solids. Her…

The late formation of chondrites as a consequence of Jupiter-induced gaps and rings

Baibhav Srivastava, André Izidoro

The accretion ages of the first planetesimals-the parent bodies of magmatic iron meteorites-suggest they formed within the first 0.5-1 Myr of Solar System history. Yet, planetesima…

Reassessing the origin and evolution of Ecliptic Comets in the Planet-9 Scenario

Rafael Ribeiro, Andre Izidoro, Alessandro Morbidelli +2

A group of newly observed extreme trans-Neptunian objects exhibit unexpected orbital confinement, characterized by the alignment of orbital angular momentum vectors and apsidal lin…

Accretion of Uranus and Neptune: confronting different giant impact scenarios

Leandro Esteves, André Izidoro, Othon C. Winter

The origins of Uranus and Neptune are not fully understood. Their inclined rotation axes -- obliquities -- suggest that they experienced giant impacts during their formation histor…

Uranus Study Report: KISS

Mark Hofstadter, Ravit Helled, David J. Stevenson +27

Determining the internal structure of Uranus is a key objective for planetary science. Knowledge of Uranus's bulk composition and the distribution of elements is crucial to underst…

Diversity of disc viscosities can explain the period ratios of resonant and non-resonant systems of hot super-Earths and mini-Neptunes

Bertram Bitsch, Andre Izidoro

Migration is a key ingredient for the formation of close-in super-Earth and mini-Neptune systems, as it sets in which resonances planets can be trapped. Slower migration rates resu…
