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, uncertainties on the underlying physics imply that some known transiting planets appear anomalously large, and this generally prevents any firm conclusion when a planet is considered on an individual basis. On the basis of a sample of nine transiting planets known at that time, Guillot et al (1996…

The formation of giant planets: constraints from interior models

Giant planets are by definition mainly made of hydrogen and helium but their precise composition is crucial to understand the processes that led to their formation, and to constrain the origins of

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

Evolution of Exoplanets and their Parent Stars

Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on

Factors affecting the radii of close-in transiting exoplanets

Context. The radius of an exoplanet may be affected by various factors, including irradiation received from the host star, the mass of the planet and its heavy element content. A significant number

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

Structure and evolution of the first CoRoT exoplanets: probing the brown dwarf/planet overlapping mass regime

We present detailed structure and evolution calculations for the first transiting extrasolar planets discovered by the space-based CoRoT mission. Comparisons between theoretical and observed radii

A transiting giant planet with a temperature between 250 K and 430 K

Transit observations of CoRoT-9b, the largest of all transiting planets, are reported, which is found to be well described by standard evolution models with an inferred interior composition consistent with that of Jupiter and Saturn.

Abstract Radial velocity planet searches have revealed that many giant planets have large eccentricities, in striking contrast with the giant planets in the solar system and prior theories of planet

The Interior Structure, Composition, and Evolution of Giant Planets

We discuss our current understanding of the interior structure and thermal evolution of giant planets. This includes the gas giants, such as Jupiter and Saturn, that are primarily composed of


There are now many known exoplanets with Msin i within a factor of 2 of Neptune's, including the transiting planets GJ 436b and HAT-P-11b. Planets in this mass range are different from their more



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.

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

THE INTERIORS OF GIANT PLANETS: Models and Outstanding Questions

▪ 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

Evolution of "51 Pegasus b-like" planets

About one-quarter of the extrasolar giant planets discovered so far have orbital distances smaller than 0.1 AU. These “51 Peg b-like” planets can now be directly characterized, as shown by the planet

Possible Solutions to the Radius Anomalies of Transiting Giant Planets

We calculate the theoretical evolution of the radii of all 14 of the known transiting extrasolar giant planets (EGPs) for a variety of assumptions concerning atmospheric opacity, dense inner core

The Evolution of Irradiated Planets: Application to Transits

Extending the theory that we derived recently for HD 209458b to different cases of strongly irradiated gaseous exoplanets, we have calculated the consistent evolution of a new transiting planet,

Interpreting and predicting the yield of transit surveys: Giant planets in the OGLE fields

Transiting extrasolar planets are now discovered jointly by photometric surveys and by radial velocimetry. We want to determine whether the different data sets are compatible between themselves and

On the Origin of HD 149026b

The high density of the recently discovered close-in extrasolar planet HD 149026b suggests the presence of a huge core in its interior, which challenges planet formation theory. We first derive

On the surface heating of synchronously spinning short-period jovian planets

We consider the atmospheric flow on short-period extrasolar planets through two-dimensional numerical simulations of hydrodynamics with radiation transfer. The observed low eccentricity of these

Models of giant planet formation with migration and disc evolution

We present a new model of giant planet formation that extends the core-accretion model of Pollack et al. (1996, Icarus, 124, 62) to include migration, disc evolution and gap formation. We show that
