Composition and fate of short-period super-Earths: The case of CoRoT-7b
- D. Valencia, M. Ikoma, T. Guillot, N. Nettelmann
- Physics
- 17 July 2009
The discovery of CoRoT-7b, a planet of radius 1.68 +/- 0.09 R_E, mass 4.8 +/- 0.8 M_E and orbital period of 0.854 days demonstrates that small planets can orbit extremely close to their star. We use… Expand
Ab Initio Simulations for Material Properties along the Jupiter Adiabat
We determine basic thermodynamic and transport properties of hydrogen-helium-water mixtures for the extreme conditions along Jupiter's adiabat via ab initio simulations, which are compiled in an… Expand
COMPOSITIONAL DIVERSITY IN THE ATMOSPHERES OF HOT NEPTUNES, WITH APPLICATION TO GJ 436b.
- J. Moses, M. Line, +6 authors N. Madhusudhan
- Physics, Medicine
- The Astrophysical journal
- 21 June 2013
Neptune-sized extrasolar planets that orbit relatively close to their host stars - often called "hot Neptunes" - are common within the known population of exoplanets and planetary candidates. Similar… Expand
New indication for a dichotomy in the interior structure of Uranus and Neptune from the application of modified shape and rotation data
- N. Nettelmann, R. Helled, J. Fortney, R. Redmer
- Physics
- 10 July 2012
Abstract Since the Voyager fly-bys of Uranus and Neptune, improved gravity field data have been derived from long-term observations of the planets' satellite motions, and modified shape and… Expand
SELF-CONSISTENT MODEL ATMOSPHERES AND THE COOLING OF THE SOLAR SYSTEM'S GIANT PLANETS
- J. Fortney, M. Ikoma, N. Nettelmann, T. Guillot, M. Marley
- Physics
- 3 January 2011
We compute grids of radiative-convective model atmospheres for Jupiter, Saturn, Uranus, and Neptune over a range of intrinsic fluxes and surface gravities. The atmosphere grids serve as an upper… Expand
The phase diagram of water and the magnetic fields of Uranus and Neptune
- R. Redmer, T. Mattsson, N. Nettelmann, M. French
- Physics
- 2011
Abstract The interior of giant planets can give valuable information on formation and evolution processes of planetary systems. However, the interior and evolution of Uranus and Neptune is still… Expand
AB INITIO EQUATION OF STATE DATA FOR HYDROGEN, HELIUM, AND WATER AND THE INTERNAL STRUCTURE OF JUPITER
- N. Nettelmann, B. Holst, A. Kietzmann, M. French, R. Redmer, D. Blaschke
- Physics
- 6 December 2007
The equation of state of hydrogen, helium, and water affects interior structure models of giant planets significantly. We present a new equation of state data table, LM-REOS, generated by large-scale… Expand
THERMAL EVOLUTION AND STRUCTURE MODELS OF THE TRANSITING SUPER-EARTH GJ 1214b
- N. Nettelmann, J. Fortney, U. Kramm, R. Redmer
- Physics
- 1 October 2010
The planet GJ 1214b is the second known super-Earth with a measured mass and radius. Orbiting a quiet M star, it receives considerably less mass-loss driving X-ray and UV radiation than CoRoT-7b, so… Expand
Saturn layered structure and homogeneous evolution models with different EOSs
- N. Nettelmann, R. Püstow, R. Redmer
- Physics
- 17 April 2013
Abstract The core mass of Saturn is commonly assumed to be 10–25 M ⊕ as predicted by interior models with various equations of state (EOSs) and the Voyager gravity data, and hence larger than that of… Expand
A FRAMEWORK FOR CHARACTERIZING THE ATMOSPHERES OF LOW-MASS LOW-DENSITY TRANSITING PLANETS
- J. Fortney, C. Mordasini, N. Nettelmann, E. Kempton, T. Greene, K. Zahnle
- Physics
- 18 June 2013
We perform modeling investigations to aid in understanding the atmospheres and composition of small planets of ~2-4 Earth radii, which are now known to be common in our Galaxy. GJ 1214b is a… Expand
