Formation of the terrestrial planets in the solar system around 1 au via radial concentration of planetesimals [PDF]
Astronomy and Astrophysics, 2018 Context. No planets exist inside the orbit of Mercury and the terrestrial planets of the solar system exhibit a localized configuration. According to thermal structure calculation of protoplanetary disks, a silicate condensation line (~1300 K) is located around 0.1 au from the Sun except for the early phase of disk evolution, and planetesimals could ...

Impact bombardment of the terrestrial planets and the early history of the Solar System
Nature Geoscience, 2013About 4 billion years ago, the terrestrial planets were bombarded by asteroids following an orbital shake-up of the outer Solar System. Lunar samples, planetary cratering records and dynamical models piece together an increasingly coherent view of this bombardment interval.

Astrophysical Journal, 2012 A model of coupled mantle convection and planetary tectonics is used to demonstrate that history dependence can outweigh the effects of a planet's energy content and material parameters in determining its tectonic state. The mantle convection-surface tectonics system allows multiple tectonic modes to exist for equivalent planetary parameter values. The

Late Accretion and the Origin of Water on Terrestrial Planets in the Solar System
2021<p>Terrestrial planets in the Solar system generally lack surface liquid water. Earth is at odd with this observation and with the idea of the giant Moon-forming impact that should have vaporized any pre-existing water, leaving behind a dry Earth.

Atmospheric Escape from Solar System Terrestrial Planets and Exoplanets
Annual Review of Earth and Planetary Sciences, 2015It has been known for decades that atmospheric escape is important for the evolution of terrestrial planets in the Solar System, although exactly how atmospheric escape changes the atmospheres of these bodies is still hotly debated. Rapidly increasing numbers of exoplanet observations provide new targets against which atmospheric escape models are ...

A Postulated Planetary Collision, the Terrestrial Planets, the Moon and Smaller Solar-System Bodies
Earth, Moon and Planets, 2013In a scenario produced by the Capture Theory of planetary formation, a collision between erstwhile solar-system giant planets, of masses 798.75 and 598.37 M⊕, is simulated using smoothed-particle hydrodynamics. Due to grain-surface chemistry that takes place in star-forming clouds, molecular species containing hydrogen, with a high D/H ratio taken as 0.

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 ...

Orbital stability of massive protoplanets in the terrestrial planet region of the solar system
The Moon and the Planets, 1978A number of theories of the formation of the planets advocate that the terrestrial planets were originally of cosmic composition and that it is only subsequent evolution that has removed their volatile components. This paper shows that such protoplanets could have remained in the terrestrial planet region without significant changes occurring in their ...

Red terrestrial planets: Searching for evidence for life beyond the Solar System
2021Red 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.
