The evolutionary divergence of Mars, Venus and Earth

Keiko Hamano, Cedric Gillmann, Gregor J. Golabek +2

Mars, Venus and Earth are expected to have started in a hot molten state. Here, we discuss how these three terrestrial planets diverged in their evolution and what mechanisms could…

Venus

Cedric Gillmann, Giada N. Arney, Guillaume Avice +6

After decades of relative neglect, interest in Venus surges anew in the planetary science community and the public. New missions are planned and selected, and will pave the way to…

An improved model of metal/silicate differentiation during Earth's accretion

K. I. Dale, D. C. Rubie, M. Nakajima +5

We improved the algorithm presented in Rubie et al. (2015) to model the chemical evolution of Earth driven by iron/silicate differentiation during the planet's accretion. The press…

Investigating the Feasibility of an Impact-Induced Martian Dichotomy

Harry A. Ballantyne, Martin Jutzi, Gregor J. Golabek +4

A giant impact is commonly thought to explain the dramatic contrast in elevation and crustal thickness between the two hemispheres of Mars known as the "Martian Dichotomy". Initial…

The long-term evolution of the atmosphere of Venus: processes and feedback mechanisms

Cedric Gillmann, M. J. Way, Guillaume Avice +11

This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its composition by interior-exterior cycling. The formation and evolution of Venus's atmosph…

Modification of icy planetesimals by early thermal evolution and collisions: Constraints for formation time and initial size of comets and small KBOs

Gregor Golabek, Martin Jutzi

Comets and small Kuiper belt objects are considered to be among the most primitive objects in the solar system as comets like C/1995 O1 Hale-Bopp are rich in highly volatile ices l…

Bifurcation of planetary building blocks during Solar System formation

Tim Lichtenberg, Joanna Drazkowska, Maria Schönbächler +2

Geochemical and astronomical evidence demonstrate that planet formation occurred in two spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We u…

Dry Late Accretion inferred from Venus' coupled atmosphere and internal evolution

C. Gillmann, G. J. Golabek, S. N. Raymond +4

The composition of meteoritic material delivered to the terrestrial planets after the end of core formation as late accretion remains contentious. Because the evolution of Venus' a…

Scaling laws for the geometry of an impact-induced magma ocean

Miki Nakajima, Gregor J. Golabek, Kai Wünnemann +6

Here, we develop scaling laws for (1) the distribution of impact-induced heat within the mantle and (2) shape of the impact-induced melt based on more than 100 smoothed particle hy…

Planet formation: The case for large efforts on the computational side

Wladimir Lyra, Thomas Haworth, Bertram Bitsch +54

Modern astronomy has finally been able to observe protoplanetary disks in reasonable resolution and detail, unveiling the processes happening during planet formation. These observe…

A water budget dichotomy of rocky protoplanets from Al-heating

Tim Lichtenberg, Gregor J. Golabek, Remo Burn +4

In contrast to the water-poor inner solar system planets, stochasticity during planetary formation and order of magnitude deviations in exoplanet volatile contents suggest that roc…

Late metal-silicate separation on the IAB parent asteroid: Constraints from combined W and Pt isotopes and thermal modelling

Alison C. Hunt, David L. Cook, Tim Lichtenberg +4

The short-lived Hf-W decay system is a powerful chronometer for constraining the timing of metal-silicate separation and core formation in planetesimals and planets…

Magma ascent in planetesimals: control by grain size

Tim Lichtenberg, Tobias Keller, Richard F. Katz +2

Rocky planetesimals in the early solar system melted internally and evolved chemically due to radiogenic heating from Al-26. Here we quantify the parametric controls on magma genes…

Water and the interior structure of terrestrial planets and icy bodies

Julien Monteux, Gregor J. Golabek, David C. Rubie +2

Water content and the internal evolution of terrestrial planets and icy bodies are closely linked. The distribution of water in planetary systems is controlled by the temperature s…

Impact splash chondrule formation during planetesimal recycling

Tim Lichtenberg, Gregor J. Golabek, Cornelis P. Dullemond +3

Chondrules are the dominant bulk silicate constituent of chondritic meteorites and originate from highly energetic, local processes during the first million years after the birth o…

Coupling SPH and thermochemical models of planets: Methodology and example of a Mars-sized body

Gregor J. Golabek, Alexandre Emsenhuber, Martin Jutzi +2

Giant impacts have been suggested to explain various characteristics of terrestrial planets and their moons. However, so far in most models only the immediate effects of the collis…

The effects of short-lived radionuclides and porosity on the early thermo-mechanical evolution of planetesimals

Tim Lichtenberg, Gregor J. Golabek, Taras V. Gerya +1

The thermal history and internal structure of chondritic planetesimals, assembled before the giant impact phase of chaotic growth, potentially yield important implications for the…

N-body simulations of oligarchic growth of Mars: Implications for Hf-W chronology

Ryuji Morishima, Gregor Golabek, Henri Samuel

Dauphas and Pourmand (2011) [Nature 473, 489--492] estimated the accretion timescale of Mars to be 1.8 Myr from the W isotopes of martian meteorites. This timescal…
