A giant impact is an increasingly popular explanation for the formation of the northern lowland on Mars. It is plausible that at the impact time both Mars and the impactor were differentiated with solid silicate mantles and liquid iron cores. Such a large impact likely resulted in merging of the cores of both bodies, a process which will have implications on the thermal state of the planet. We model the evolution of the Martian mantle following a giant impact and characterize the thermochemical… 

The history of the core dynamos of Mars and the Moon inferred from their crustal magnetization: a brief review

The core dynamos of Mars and the Moon have distinctly different histories. Mars had no core dynamo at the end of accretion. It took ∼100 Myr for the core to create a strong dynamo that magnetized the

Hadean/Eoarchean tectonics and mantle mixing induced by impacts: a three-dimensional study

The timing of the onset of plate tectonics on Earth remains a topic of strong debate, as does the tectonic mode that preceded modern plate tectonics. Understanding possible tectonic modes and

Formation of a solid inner core during the accretion of Earth

The formation of an inner core during the accretion of Earth is investigated by using self‐gravitating and compressible Earth models formed by accreting a total of 25 or 50 Moon to Mars‐sized

Dynamical effects of multiple impacts: Large impacts on a Mars-like planet



Giant impacts on early Mars and the cessation of the Martian dynamo

[1] Although Mars currently has no global dynamo-driven magnetic field, widespread crustal magnetization provides strong evidence that such a field existed in the past. The absence of magnetization

Life of the Martian dynamo

Giant impact stratification of the Martian core

We investigate the direct thermal effects of giant impacts on the Martian core and its dynamo. Shock wave heating of Mars is calculated in terms of the impact velocity and the final basin size.

The effect of the Caloris impact on the mantle dynamics and volcanism of Mercury

[1] The MESSENGER spacecraft has imaged more than 95% of the surface of Mercury. Images of the Caloris impact basins, along with several smaller impact structures, reveal evidence for volcanic plains

Magma ocean formation due to giant impacts

Current understanding of the last stages of planetary accretion suggests that mass and energy accumulation are dominated by a few large impacts. An important thermal consequence of such impacts is
