The solar system, as we know it today, is about 4.5 billion years old. It is widely believed that it was essentially completed 100 million years after the formation of the Sun, which itself took less than 1 million years, although the exact chronology remains highly uncertain. For instance: which, of the giant planets or the terrestrial planets, formed first, and how? How did they acquire their mass? What was the early evolution of the “primitive solar nebula” (solar nebula for short)? What is… 
The abundance of 26Al-rich planetary systems in the Galaxy
One of the most puzzling properties of the solar system is the high abundance at its birth of 26Al, a short-lived radionuclide with a mean life of 1 Myr. Now decayed, it has left its imprint in
Origin and evolution of the atmospheres of early Venus, Earth and Mars
We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the time when their accreting bodies were released from the protoplanetary disk a few million years after the
A Perspective from Extinct Radionuclides on a Young Stellar Object: The Sun and Its Accretion Disk
Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our knowledge about the
Two Different Sources of Water for the Early Solar Nebula
The chemical mechanics for water formation and its expected abundance are explored by studying the parental cloud core of the solar nebula and its gravitational collapse and the dependence of the production of water on the initial abundance ratio between carbon and oxygen is analysed.
The Origin of Short-lived Radionuclides and the Astrophysical Environment of Solar System Formation
Based on early solar system abundances of short-lived radionuclides (SRs), such as 26Al (T1/2 = 0.74 Myr) and 60Fe (T1/2 = 1.5 Myr), it is often asserted that the Sun was born in a large stellar
Formation and Evolution of Protoatmospheres
The origin and evolution of planetary protoatmospheres in relation to the protoplanetary disk is discussed. The initial atmospheres of planets can mainly be related via two formation scenarios. If a
The influence of melting on the thermo-chemical evolution of rocky planets' interiors
The last couple of years have seen a surge in the discovery of extra-solar terrestrial planets. Some of these planets orbit their stars within the so-called habitable zone, which has raised questions
The radioactive isotope 60Fe (T1/2 = 1.5 Myr) was present in the early solar system. It is unlikely that it was injected directly into the nascent solar system by a single, nearby supernova (SN). It


A short timescale for terrestrial planet formation from Hf–W chronometry of meteorites
Measurements of tungsten isotope compositions and hafnium–tungsten ratios of several meteorites indicate that the bulk of metal–silicate separation in the Solar System was completed within <30 Myr, completely consistent with other evidence for rapid planetary formation.
The formation of planetesimals.
Four stages in the accretion of planetesimals are described. The initial stage is the condensation of dust particles from the gaseous solar nebula as it cools. These dust particles settle into a thin
Short-Lived Nuclei in the Early Solar System: A Low Mass Stellar Source?
Abstract We discuss possible stellar origins of short-lived radioactive nuclei with meanlife τ ≤ 100 Myr, which were shown to be alive in the Early Solar System (ESS). We first review current ideas
Formation of the Giant Planets by Concurrent Accretion of Solids and Gas
New numerical simulations of the formation of the giant of the second phase. planets are presented, in which for the first time both the gas and The actual rates at which the giant planets accreted
The Accretion, Composition and Early Differentiation of Mars
The early development of Mars is of enormous interest, not just in its own right, but also because it provides unique insights into the earliest history of the Earth, a planet whose origins have been
Planets in the asteroid belt
Abstract— The main asteroid belt has lost >99.9% of its solid mass since the time at which the planets were forming, according to models for the protoplanetary nebula. Here we show that the
Hafnium–tungsten chronometry and the timing of terrestrial core formation
THE accretion of the Earth and Moon within the solar nebula is thought1–3 to have taken 50 to 100 million years. But the timing of formation of the Earth's core has been controversial, with some4,5
Making More Terrestrial Planets
The results of 16 new 3D N-body simulations of the final stage of the formation of the terrestrial planets are presented. These Nbody integrations begin with 150‐160 lunar-to-Mars size planetary
Formation of the Earth
The origin of the earth is discussed in the context of the formation of the sun and the planets, and a standard model for such a formation assuming gravitational instability in a dense interstellar
The Primordial Excitation and Clearing of the Asteroid Belt
Abstract In this paper, we use N -body integrations to study the effect that planetary embryos spread between ∼0.5 and 4 AU would have on primordial asteroids. The most promising model for the
