Shock Events in the Solar System: The Message from Minerals in Terrestrial Planets and Asteroids
Annual Review of Earth and Planetary Sciences, 2013 Impacts are central to the origin and evolution of planets of the Solar System. The shapes of craters, which can reach up to 1,000 km in diameter on the Moon, provide critical information on the large-scale dynamics of the impact and related shock. Minerals formed at high pressure and temperature found in shocked terrestrial rocks and meteorites give ...

Chromium isotopic insights into early solar system evolution and origin of terrestrial planets
, 2021 Les isotopes du chrome (Cr) jouent un rôle important dans la cosmochimie et les sciences planétaires car ce sont de puissants outils pour dater (chronométrie de courte période 53Mn-53Cr), tracer (anomalies nucléosynthétiques 54Cr) les origines des matériaux, et étudier les processus impliqués dans le fractionnement des éléments volatils et la ...

Icarus, 2014 In order to test planetary accretion and differentiation scenarios, we integrated a multistage core-mantle differentiation model with N-body accretion simulations. Impacts between embryos and planetesimals result in magma ocean formation and episodes of core formation. The core formation model combines rigorous chemical mass balance with metal-silicate

Red terrestrial planets: Searching for evidence for life beyond the Solar System
, 2020 Red dwarfs, which are stars that are typically born with masses below 0.6 Msun, are the most numerous stars and comprise about 70% of the stellar population in the Solar neighbourhood. Since we rely on indirect methods for detection of exoplanets, this small stars provide a number of advantages for the detection of the smallest planets.

Observations of Locally Generated Whistler-mode Waves in the Martian Magnetotail Current Sheet
The Astrophysical Journal, 2023 The whistler-mode wave is an electromagnetic wave that commonly occurs in space plasma and has been extensively studied, especially within the Earth's magnetosphere. They have also been reported in the near-Mars space, such as Martian upstream solar wind,

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System
The Astronomical Journal, 2023 The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.
