Oxidation Constraints on Terrestrial Planet Formation from a Ring
Katherine I. Dale, Alessandro Morbidelli, Gabriel Nathan +3
The present-day solar system comprises meteorites with varying oxidation levels, derived from different parent bodies. Previous studies (e.g. Rubie et al., 2011) of the partitionin…
Terrestrial planet formation from a ring: long-term simulations accounting for the giant planet instability
J. M. Y. Woo, D. Nesvorny, J. Scora +1
The process leading to the formation of the terrestrial planet remains elusive. In a previous publication, we have shown that, if the first generation of planetesimals forms in a r…
Terrestrial planet formation from a ring
J. M. Y. Woo, A. Morbidelli, S. L. Grimm +2
It has been long proposed that, if all the terrestrial planets form within a tiny ring of solid material at around 1 AU, the concentrated mass-distance distribution of the current…
Evidence of a primordial isotopic gradient in the inner region of the solar protoplanetary disc
J. Mah, R. Brasser, J. M. Y. Woo +2
Not only do the sampled terrestrial worlds (Earth, Mars, and asteroid 4 Vesta) differ in their mass-independent (nucleosynthetic) isotopic compositions of many elements (e.g. $\var…
The terrestrial planet formation paradox inferred from high-resolution N-body simulations
Jason Man Yin Woo, Ramon Brasser, Simon L. Grimm +2
Recent improvements to GPU hardware and the symplectic N-body code GENGA allow for unprecedented resolution in simulations of planet formation. In this paper, we report results fro…
Did Uranus' regular moons form via a rocky giant impactor?
Jason Man Yin Woo, Christian Reinhardt, Marco Cilibrasi +3
The formation of Uranus' regular moons has been suggested to be linked to the origin of its enormous spin axial tilt (~98^o). A giant impact between proto-Uranus and a 2-3 M_Earth…
Mars' formation can constrain the primordial orbits of the gas giants
Jason Man Yin Woo, Joachim Stadel, Simon Grimm +1
Recent high precision meteoritic data infers that Mars finished its accretion rapidly within 10 Myr of the beginning of the Solar system and had an accretion zone that did not enti…
Growing Mars fast: High-resolution GPU simulations of embryo formation
Jason Man Yin Woo, Simon L. Grimm, Ramon Brasser +1
Recent high precision meteoritic data improve constraints on the formation timescale and bulk composition of the terrestrial planets. High resolution N-body simulations allow direc…
A Numerical Method for Determining the Elements of Circumbinary Orbits and Its Application to Circumbinary Planets and the Satellites of Pluto-Charon
Jason Man Yin Woo, Man Hoi Lee
Planets and satellites orbiting a binary system exist in the solar system and extrasolar planetary systems. Their orbits can be significantly different from Keplerian orbits, if th…
Mars in the aftermath of a colossal impact
Jason Man Yin Woo, Hidenori Genda, Ramon Brasser +1
The abundance of highly siderophile elements (HSEs) inferred for Mars' mantle from martian meteorites implies a Late Veneer (LV) mass addition of ~0.8 wt% with broadly chondritic c…
The curious case of Mars formation
Jason Man Yin Woo, Ramon Brasser, Soko Matsumura +2
Dynamical models of planet formation coupled with cosmochemical data from martian meteorites show that Mars' isotopic composition is distinct from that of Earth. Reconciliation of…
On the Early In Situ Formation of Pluto's Small Satellites
Man Yin Woo, Man Hoi Lee
The formation of Pluto's small satellites - Styx, Nix, Keberos and Hydra - remains a mystery. Their orbits are nearly circular and are near mean-motion resonances and nearly coplan…
