▪ Abstract We know that giant planets played a crucial role in the making of our Solar System. The discovery of giant planets orbiting other stars is a formidable opportunity to learn more about these objects, what their composition is, how various processes influence their structure and evolution, and most importantly how they form. Jupiter, Saturn, Uranus, and Neptune can be studied in detail, mostly from close spacecraft flybys. We can infer that they are all enriched in heavy elements… 
The physical properties of extra-solar planets
Tremendous progress in the science of extrasolar planets has been achieved since the discovery of a Jupiter orbiting the nearby Sun-like star 51 Pegasi in 1995. Theoretical models have now reached
Spectroscopy of planetary atmospheres in our Galaxy
About 20 years after the discovery of the first extrasolar planet, the number of planets known has grown by three orders of magnitude, and continues to increase at neck breaking pace. For most of
The composition of transiting giant extrasolar planets
In principle, the combined measurements of the mass and radius of a giant exoplanet allow one to determine the relative fraction of hydrogen and helium and of heavy elements in the planet. However,
Saturn ’ s Exploration Beyond
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the
A new vision on (Extrasolar) Giant Planets Internal Structure and Evolution
The detection and characterization of extrasolar planets clearly appears as one of the main goals of observational astronomy for the coming years. Space and ground project are numerous, but
Terrestrial planets in high-mass disks without gas giants
Context. Observational and theoretical studies suggest that planetary systems consisting only of rocky planets are probably the most common in the Universe. Aims. We study the potential habitability
The Formation and Dynamics of Super-Earth Planets
Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have
The fuzziness of giant planets' cores
Giant planets are thought to have cores in their deep interiors, and the division into a heavy-element core and hydrogen–helium envelope is applied in both formation and structure models. We show


Interiors of giant planets inside and outside the solar system.
An understanding of the structure and composition of the giant planets is rapidly evolving because of (i) high-pressure experiments with the ability to study metallic hydrogen and define the
Interiors of the Giant Planets
From our position as inhabitants of a rather insignificant rock orbiting close in to the Sun, there is an inevitable tendency to think of the giant planets (Jupiter, Saturn, Uranus, and Neptune) as
Where Are the Massive Close-in Extrasolar Planets?
About 68 extrasolar planets around main-sequence stars of spectral types F, G, and K have been discovered up to now. The minimum masses (Mp sin i) of these planets are ranging from fractions of a
A low-temperature origin for the planetesimals that formed Jupiter
It is shown that argon, krypton and xenon in Jupiter's atmosphere are enriched to the same extent as the other heavy elements, which suggests that the planetesimals carrying these elements must have formed at temperatures lower than predicted by present models of giant-planet formation.
Giant Planets at Small Orbital Distances
Using Doppler spectroscopy to detect the reflex motion of the nearby star, 51 Pegasi, Mayor & Queloz (1995) claim to have discovered a giant planet in a 0.05 AU, 4.23 day orbit. They estimate its
Implications of Extrasolar Planets for Understanding Planet Formation
▪ Abstract The observed properties of extrasolar planets and planetary systems are reviewed, including discussion of the mass, period, and eccentricity distributions; the presence of multiple
On the Radii of Extrasolar Giant Planets
We have computed evolutionary models for extrasolar planets that range in mass from 0.1MJ to 3.0MJ and that range in equilibrium temperature from 113 to 2000 K. We present four sequences of models,
On the Radii of Close-in Giant Planets
It is found that HD 209458b must be a hydrogen-rich gas giant and the large radius of a close-in gas giant is not due to the thermal expansion of its atmosphere but to the high residual entropy that remains throughout its bulk by dint of its early proximity to a luminous primary.
A Theory of Extrasolar Giant Planets
We present a broad suite of models of extrasolar giant planets (EGP's), ranging in mass from 0.3 to 15 Jupiter masses. The models predict luminosity (both reflected and emitted) as a function of age,

New three-dimensional, "locally isothermal," hydrodynamical models without velocity damping show that a disk instability can form Jupiter-mass clumps, implying that disk instability could obviate the core accretion mechanism in the solar nebula and elsewhere.
