Comparison of Jupiter Interior Models Derived from First-Principles Simulations
B. Militzer, W. B. Hubbard
Recently two groups used first-principles computer simulations to model Jupiter's interior. While both studies relied on the same simulation technique, density functional molecular…
A Massive Core in Jupiter Predicted From First-Principles Simulations
B. Militzer, W. B. Hubbard, J. Vorberger +2
Hydrogen-helium mixtures at conditions of Jupiter's interior are studied with first-principles computer simulations. The resulting equation of state (EOS) implies that Jupiter poss…
A Mass Function Constraint on Extrasolar Giant Planet Evaporation Rates
W. B Hubbard, M. Hattori, A. Burrows +1
The observed mass function for all known extrasolar giant planets (EGPs) varies approximately as M^{-1} for mass M between 0.2 Jupiter masses (M_J) and 5 M_J. In order to study eva…
Possible Solutions to the Radius Anomalies of Transiting Giant Planets
A. Burrows, I. Hubeny, J. Budaj +1
We calculate the theoretical evolution of the radii of all fourteen of the known transiting extrasolar giant planets (EGPs) for a variety of assumptions concerning atmospheric opac…
Theoretical Radii of Transiting Giant Planets: The Case of OGLE-TR-56b
A. Burrows, I. Hubeny, W. B. Hubbard +2
We calculate radius versus age trajectories for the photometrically-selected transiting extrasolar giant planet, OGLE-TR-56b, and find agreement between theory and observation, wit…
Effects of Helium Phase Separation on the Evolution of Extrasolar Giant Planets
Jonathan J. Fortney, W. B. Hubbard
We build on recent new evolutionary models of Jupiter and Saturn and here extend our calculations to investigate the evolution of extrasolar giant planets of mass 0.15 to 3.0 M_J.…
A Theory for the Radius of the Transiting Giant Planet HD 209458b
Adam Burrows, David Sudarsky, William B. Hubbard
Using a full frequency-dependent atmosphere code that can incorporate irradiation by a central primary star, we calculate self-consistent boundary conditions for the evolution of t…
The Theory of Brown Dwarfs and Extrasolar Giant Planets
Adam Burrows, W. B. Hubbard, J. I. Lunine +1
Straddling the traditional realms of the planets and the stars, objects below the edge of the main sequence have such unique properties, and are being discovered in such quantities…
Theory of Extrasolar Giant Planet Transits
W. B. Hubbard, J. J. Fortney, J. I. Lunine +3
We present a synthesis of physical effects influencing the observed lightcurve of an extrasolar giant planet (EGP) transiting its host star. The synthesis includes a treatment of R…
On the Radii of Close-in Giant Planets
A. Burrows, T. Guillot, W. B. Hubbard +4
The recent discovery that the close-in extrasolar giant planet, HD209458b, transits its star has provided a first-of-its-kind measurement of the planet's radius and mass. In additi…
Comparative Evolution of Jupiter and Saturn
W. B. Hubbard, T. Guillot, M. S. Marley +3
We present evolutionary sequences for Jupiter and Saturn, based on new nongray model atmospheres, which take into account the evolution of the solar luminosity and partitioning of…
A Non-Gray Theory of Extrasolar Giant Planets and Brown Dwarfs
A. Burrows, M. Marley, W. B. Hubbard +6
We present the results of a new series of non-gray calculations of the atmospheres, spectra, colors, and evolution of extrasolar giant planets (EGPs) and brown dwarfs for effective…
Extrasolar Giant Planet and Brown Dwarf Models
A. Burrows, W. B. Hubbard, J. I. Lunine +3
With the discovery of the companions of 51 Peg, 55 Cnc, Boo, And, 70 Vir, 47 UMa, and Gl229, evolutionary and spectral models of gas giants and/or brown dwarfs with…
Liquid metallic hydrogen and the structure of brown dwarfs and giant planets
W. B. Hubbard, T. Guillot, J. I. Lunine +4
Electron-degenerate, pressure-ionized hydrogen (usually referred to as metallic hydrogen) is the principal constituent of brown dwarfs, the long-sought objects which lie in the mas…
Theortetical Models of Extrasolar Giant Planets
A. Burrows, W. B. Hubbard, J. I. Lunine +4
The recent discoveries of giant planets around nearby stars have galvanized the planetary science community, astronomers, and the public at large. Since {\it direct} detection is n…
Atmospheric, Evolutionary, and Spectral Models of the Brown Dwarf Gliese 229 B
M. S. Marley, D. Saumon, T. Guillot +4
Theoretical spectra and evolutionary models that span the giant planet--brown dwarf continuum have been computed based on the recent discovery of the brown dwarf, Gliese 229 B. A f…
Giant Planets at Small Orbital Distances
T. Guillot, A. Burrows, W. B. Hubbard +2
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-A.U., 4.23-day orbit.…
A Theory of Extrasolar Giant Planets
D. Saumon, W. B. Hubbard, A. Burrows +3
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…
