The Dynamical Consequences of a Super-Earth in the Solar System

The Planetary Science Journal, 2023
Placing the architecture of the solar system within the broader context of planetary architectures is one of the primary topics of interest within planetary science. Exoplanet discoveries have revealed a large range of system architectures, many of which

Mercury’s Hidden Past: Revealing a Volatile-dominated Layer through Glacier-like Features and Chaotic Terrains

The Planetary Science Journal, 2023
The discovery of global elemental volatile compositions, sublimation hollows, and chaotic terrains has significantly reshaped our understanding of Mercury’s geology.

Outgassing Composition of the Murchison Meteorite: Implications for Volatile Depletion of Planetesimals and Interior-atmosphere Connections for Terrestrial Exoplanets

The Planetary Science Journal, 2023
Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system.

Origin of life-forming volatile elements in the inner Solar System [PDF]

, 2022
International audienceVolatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated.

Mars and Terrestrial Planet Habitability [PDF]

, 2021
What allows a planet to be both within a potentially habitable zone and sustain habitability over long geologic time? With the advent of exoplanetary astronomy and the ongoing discovery of terrestrial‐type planets around other stars, our own solar system

Terrestrial planet compositions controlled by accretion disk magnetic field

Progress in Earth and Planetary Science, 2021
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ices, and, for the Earth, liquid water.

Terrestrial planet formation in extra-solar planetary systems [PDF]

Proceedings of the International Astronomical Union, 2007
AbstractTerrestrial planets form in a series of dynamical steps from the solid component of circumstellar disks. First, km-sized planetesimals form likely via a combination of sticky collisions, turbulent concentration of solids, and gravitational collapse from micron-sized dust grains in the thin disk midplane.

Modelling Atmospheric Erosion for Terrestrial Planets in the Solar System

, 2023
Since the Great Oxidation Event, the oxygen escape rate on Earth has changed over time mainly due to solar evolution. Two solar agents drive the Earth’s atmospheric erosion rate: the solar wind and the EUV radiation. The first one affects the non-thermal processes by changing the plasma conditions, and the second one affects both types of processes: by

Overview of electric solar wind sail applications; pp. 267–278 [PDF]

Proceedings of the Estonian Academy of Sciences, 2014
We analyse the potential of the electric solar wind sail for solar system space missions. The applications studied include flyby missions to terrestrial planets (Venus, Mars and Phobos, Mercury) and asteroids, missions based on non-Keplerian orbits ...
