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…
Numerical Insights into Disk Accretion, Eccentricity, and Kinematics in the Class 0 phase
Adnan Ali Ahmad, Benoît Commerçon, Elliot Lynch +4
The formation and early evolution of protoplanetary disks are governed by a wide variety of physical processes during a gravitational collapse. Observations have begun probing disk…
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…
