Terrestrial planets, with silicate mantles and metallic cores, are likely to obtain water and carbon compounds during accretion. Here I examine the conditions that allow early formation of a surface water ocean (simultaneous with cooling to clement surface conditions), and the timeline of degassing the planetary interior into the atmosphere. The greatest fraction of a planet’s initial volatile budget is degassed into the atmosphere during the end of magma ocean solidification, leaving only a… 

Water Partitioning in Planetary Embryos and Protoplanets with Magma Oceans

The water content of magma oceans is widely accepted as a key factor that determines whether a terrestrial planet is habitable. Water ocean mass is determined as a result not only of water delivery

Magma oceans in the inner solar system

Theory and observations point to the occurrence of magma ponds or oceans in the early evolution of terrestrial planets and in many early-accreting planetesimals. The apparent ubiquity of melting

Escape of the martian protoatmosphere and initial water inventory

Extreme water loss and abiotic O2 buildup on planets throughout the habitable zones of M dwarfs.

In general, it is found that the initial phase of high luminosity may compromise the habitability of many terrestrial planets orbiting low-mass stars.

Evidence for primordial water in Earth’s deep mantle

Data for Baffin Island and Icelandic lavas are presented, which suggest that the deep mantle has a low D/H ratio (δD more negative than –218 per mil), which indicates the existence of a component within Earth’s interior that inherited its D/h ratio directly from the protosolar nebula.

It is shown that water adsorbs dissociatively on the olivine {100} surface at the temperature and water pressure expected for the accretion disc, leaving an OH adlayer that is stable at least up to 900 K.


This work explores how the incorporation of different mechanisms for the degassing and regassing of water changes the volatile evolution of a planet and finds that if volatile cycling is either solely dependent on temperature or seafloor pressure, exoplanets require a high abundance of water to have fully inundated surfaces.

The deep CO2 sequestration into the mantle could be explained by a rapid subduction of the old oceanic crust, such that the top of the crust would remain cold and retain its CO2.

Pathways to Earth-Like Atmospheres

It is shown that planets even in orbits within the habitable zone of their host stars might not lose nebular- or catastrophically outgassed initial protoatmospheres completely and could end up as water worlds with CO2 and hydrogen- or oxygen-rich upper atmospheres.

Internal sources of water on Earth

Abstract Rocky planets are built through a series of highly energetic accretionary impacts. The accreting bodies are thought to carry small amounts of water to the growing planet, but it is debated

The Possibility of Catastrophic Magma Ocean Degassing and Implications for the Formation of Early Planetary Atmospheres

The heat provided by accretion and differentiation is sufficient to melt the silicate mantle of a terrestrial planet or planetary embryo wholly or partially creating magma oceans that may span a wide

The formation of an impact‐generated H2O atmosphere and its implications for the early thermal history of the Earth

During accretion of the earth by planetesimal impacts, shock degassing of volatile materials occurs, and a proto-atmosphere is formed. Once such an impact-generated atmosphere is formed, the surface

A cool early Earth?

The hypothesis of a cool early Earth suggests long intervals of relatively temperate surface conditions from 4.4 to 4.0 Ga that were conducive to liquidwater oceans and possibly life and may have been less frequent than previously thought.

Late formation and prolonged differentiation of the Moon inferred from W isotopes in lunar metals

The Moon is thought to have formed from debris ejected by a giant impact with the early ‘proto’-Earth and, as a result of the high energies involved, the Moon would have melted to form a magma ocean.

Density-wave interactions between growing planets and the gas nebula may help to explain the current near-circular orbits of the Earth and Venus, and may result in large-scale radial migration of proto-planetary embryos.

Constitution of the Terrestrial Planets

IN a paper, "On the Constitution of the Terrestrial Planets", by W. H. Ramsey (Mon. Not. Roy. Astro. Soc., 108, 5 ; 1948), it is suggested that the earth' core and mantle are not chemically distinct.

Mineralogy of the Martian interior up to core‐mantle boundary pressures

In order to determine the mineralogy of the Martian interior along a high-temperature areotherm, multianvil experiments have been performed with a model Martian mantle composition up to 23.5 GPa. The

Origin of the Earth and Moon

About 130 scientists met December 1-3, 1998, in Monterey, California, to share ideas about the formation and very early history of the Earth and Moon. Conference organizers constructed the program to
