The formation of the gas giant planets Jupiter and Saturn probably required the growth of massive ∼ 15 Earth-mass cores on a time scale shorter than the ∼ 107 time scale for removal of nebular gas. Relatively minor variations in nebular parameters could preclude the growth of full-size gas giants even in systems in which the terrestrial planet region is similar to our own. Systems containing “failed Jupiters,” resembling Uranus and Neptune in their failure to capture much nebular gas, would be… 

Jupiter: Cosmic Jekyll and Hyde.

The simulations predict that Jupiter's capacity to shield or intercept Earth-bound comets originating in the outer Solar System is poor, and that the importance of jovian planets on the formation of life is not that they act as shields, but rather that they deliver life-enabling volatiles to the terrestrial planets.

Tests of in situ Formation Scenarios for Compact Multiplanet Systems

Kepler has identified over 600 multiplanet systems, many of which have several planets with orbital distances smaller than that of Mercury. Because these systems may be difficult to explain in the

A reappraisal of the habitability of planets around M dwarf stars.

It is concluded that M dwarf stars may indeed be viable hosts for planets on which the origin and evolution of life can occur and it makes sense to include M dwarfs in programs that seek to find habitable worlds and evidence of life.

Extra-solar planets

The discovery of the first extra-solar planet surrounding a main-sequence star was announced in 1995, based on very precise radial velocity (Doppler) measurements. A total of 34 such planets were

Parent Stars of Extrasolar Planets. VII. New Abundance Analyses of 30 Systems

The results of new spectroscopic analyses of 30 stars with giant planet and/or brown dwarf companions are presented. Values for Teff and [Fe/H] are used in conjunction with Hipparcos data and Padua

Gravitational scattering as a possible origin for giant planets at small stellar distances

An alternative model for planetary migration that can account for two large orbital eccentricities of giant planets that are difficult to reconcile with a tidal-linkage model is described.

The Role of Giant Planets in Terrestrial Planet Formation

We present the results of simulations of the late stages of terrestrial planet formation under the gravitational influence of six different outer giant planetary systems with a wide range of

Quantifying Jupiter's influence on the Earth's impact flux: Implications for planetary habitability

It has long been thought that the presence of a giant planet is a pre-requisite for the development of life on potentially habitable planets. Without Jupiter, it was argued, the Earth would have been

A Cosmochemical Determinism in the Formation of Earth-like Planets

Abstract The discovery of giant planets around other Sun-like stars has stimulated interest in the search for planets capable of supporting life. Here, it is proposed that the abundance of water in


Abstract The statistical distribution of the masses of planets about stars between the Sun and the center of the Galaxy is constrained to within a factor of 3 by an intensive search for planets



Occurrence of Earth-Like Bodies in Planetary Systems

Simulations in which runaways were allowed to form in the asteroid belt show that during the growth of the planets these distributions spontaneously evolve toward those observed, simply as a result of known solar system processes.

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

Cratering of the terrestrial planets by Apollo objects

— Absolute and relative cratering rates on the terrestrial planets have been calculated using the same asteroidal collision model and Monte Carlo program used for previous studies of the terrestrial


The importance of detecting interstellar comets as an indirect indicator of the rate of planetary formation in the galaxy is discussed. The tie between interstellar comet (ISC) detection and

The Origin of Short-Period Comets

The key results of an extensive series of numerical simulations of the evolution of comet orbits due to the gravitational perturbations of the giant planets are presented. The results show that the

The distribution of mass in the planetary system and solar nebula

A model ‘solar nebula’ is constructed by adding the solar complement of light elements to each planet, using recent models of planetary compositions. Uncertainties in this approach are estimated. The
