Magnetically Driven Obliquity in Circumplanetary Disks and Twisted Bipolar-jet Formation
Raúl O. Chametla, Martin E. Pessah, F. Javier Sánchez-Salcedo +4
Circumplanetary disks (CPDs) regulate gas accretion onto forming giant planets and provide the environment in which their satellites may form. We use high-resolution, global three-…
Dust dynamics in disk dust traps and late planetesimal formation
Maya Tatarelli, Alessandro Morbidelli, Elena Lega
The streaming instability is the leading model for planetesimal formation in protoplanetary disks, but it typically operates within the first ~Myr. In the Solar System, however, so…
Two-source terrestrial planet formation with a sweeping secular resonance
Max Goldberg, David Nesvorný, Alessandro Morbidelli
The models that most successfully reproduce the orbital architecture of the Solar System terrestrial planets start from a narrow annulus of material that grows into embryos and the…
A massive primordial atmosphere on early Mars
Sarah Joiret, Alessandro Morbidelli, Rafael de Sousa Ribeiro +2
Mars finished forming while the solar nebula was still present, and acquired its primordial atmosphere from this reservoir. The absence of a detectable cometary xenon signature in…
Terrestrial Planet Formation from Two Source Reservoirs
David Nesvorny, Alessandro Morbidelli, William F. Bottke +2
This work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into…
On inertial forces (indirect terms) in problems with a central body
Aurélien Crida, Clément Baruteau, Philippine Griveaud +14
Gravitational systems in astrophysics often comprise a body -- the primary -- that far outweights the others, and which is taken as the centre of the reference frame. A fictitious…
The refractory-to-ice ratio in comet 67P: implications on the composition of the comet-forming region of the protoplanetary disk
Raphael Marschall, Alessandro Morbidelli, Yves Marrocchi
Comets, asteroids, and other small bodies are thought to be remnants of the original planetesimal population of the Solar System. As such, their physical, chemical, and isotopic pr…
Did the terrestrial planets of the Solar System form by pebble accretion?
Alessandro Morbidelli, Thorsten Kleine, Francis Nimmo
The dominant accretion process leading to the formation of the terrestrial planets of the Solar System is a subject of intense scientific debate. Two radically different scenarios…
Formation and evolution of a protoplanetary disk: combining observations, simulations and cosmochemical constraints
Alessandro Morbidelli, Yves Marrocchi, Adnan Ali Ahmad +12
We present a plausible and coherent view of the evolution of the protosolar disk that is consistent with the cosmochemical constraints and compatible with observations of other pro…
Contemporary formation of early solar system planetesimals at two distinct radial locations
Alessandro Morbidelli, Kevin Baillie, Konstantin Batygin +4
The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the p…
A record of the final phase of giant planet migration fossilized in the asteroid belt's orbital structure
Matthew S. Clement, Alessandro Morbidelli, Sean N. Raymond +1
The asteroid belt is characterized by an extreme low total mass of material on dynamically excited orbits. The Nice Model explains many peculiar qualities of the solar system, incl…
Outwards migration for planets in stellar irradiated 3D discs
E. Lega, A. Morbidelli, B. Bitsch +2
For the very first time we present 3D simulations of planets embedded in stellar irradiated discs. It is well known that thermal effects could reverse the direction of planetary mi…
Accretion of Jupiter-mass Planets in the Limit of Vanishing Viscosity
J. Szulágyi, A. Morbidelli, A. Crida +1
In the core-accretion model the nominal runaway gas-accretion phase brings most planets to multiple Jupiter masses. However, known giant planets are predominantly Jupiter-mass bodi…
Considerations on the accretion of Uranus and Neptune by mutual collisions of planetary embryos in the vicinity of Jupiter and Saturn
M. Jakubik, A. Morbidelli, L. Neslusan +1
Modeling the formation of the ice giants Uranus and Neptune is a long-lasting problem in planetary science. Due to gas-drag, collisional damping, and resonant shepherding, the plan…
