Water in the terrestrial planet-forming zone of the PDS 70 disk [PDF]
Nature, 2023 Observations with the sensitive mid-infrared spectrometer MIRI on board JWST reveal the presence of a water vapour reservoir in the terrestrial plant-forming zone of the young planetary system PDS 70.

Silicon isotope constraints on terrestrial planet accretion. [PDF]
Nature, 2023 The nucleosynthetic composition of silicon in meteorites indicates that material akin to early-formed differentiated asteroids must represent a major constituent of terrestrial planets such as Earth and Mars.

Evidence for igneous differentiation in Sudbury Igneous Complex and impact-driven evolution of terrestrial planet proto-crusts. [PDF]
Nat Commun, 2019 Bolide impact is a ubiquitous geological process in the Solar System, which produced craters and basins filled with impact melt sheets on the terrestrial planets.

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. [PDF]
Proc Natl Acad Sci U S A, 2011 Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets.

Terrestrial planet and asteroid belt formation by Jupiter–Saturn chaotic excitation [PDF]
Scientific Reports, 2023 The terrestrial planets formed by accretion of asteroid-like objects within the inner solar system’s protoplanetary disk. Previous works have found that forming a small-mass Mars requires the disk to contain little mass beyond ~ 1.5 au (i.e., the disk ...

The Terrestrial Planet Finder [PDF]
2001 IEEE Aerospace Conference Proceedings (Cat. No.01TH8542), 2002 The Terrestrial Planet Finder (TPF) is a space-based astronomical telescope that will combine high sensitivity and spatial resolution to detect and characterize /spl sim/150 planetary systems within 15 pc of our Sun. In a five-year mission, currently expected to commence in 2012, TPF will look for the atmospheric signatures of life using the methods of

Lunar and terrestrial planet formation in the Grand Tack scenario. [PDF]
Philos Trans A Math Phys Eng Sci, 2014 We present conclusions from a large number of N-body simulations of the giant impact phase of terrestrial planet formation. We focus on new results obtained from the recently proposed Grand Tack model, which couples the gas-driven migration of giant ...
