cds-question@unistra.frexoplanetsbrown-dwarfsmetallicitymagnetic-fieldsastronomical-modelsWe present thermodynamic material and transport properties for the extreme conditions prevalent in the interiors of massive giant planets and brown dwarfs. They are obtained from extensive ab initio simulations of hydrogen-helium mixtures along the isentropes of three representative objects. In particular, we determine the heat capacities, the thermal expansion coefficient, the isothermal compressibility, and the sound velocity. Important transport properties such as the electrical and thermal conductivity, opacity, and shear viscosity are also calculated. Further results for associated quantities, including magnetic and thermal diffusivity, kinematic shear viscosity, as well as the static Love number k_2_ and the equidistance, are presented. In comparison to Jupiter-mass planets, the behavior inside massive giant planets and brown dwarfs is stronger dominated by degenerate matter. We discuss the implications on possible dynamics and magnetic fields of those massive objects. The consistent data set compiled here may serve as a starting point to obtain material and transport properties for other substellar H-He objects with masses above one Jovian mass and finally may be used as input for dynamo simulations.2018AJ....156..149Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/149CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/491/889 : CoRoT-Exo-3b observations (Deleuil+, 2008)J/ApJ/764/18 : Characteristic frequencies of giant exoplanetsJ/ApJS/215/21 : Hydrogen and Helium EOS in brown dwarfs (Becker+, 2014)J/A+A/615/A39 : Exoplanets interior structures & Love numbershttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/149https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/156/149/table1 (Observational constraints and parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/149/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/149/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/149/table1?GETtext/xml+votable180.050000true291.137583336.57736110.0055555555555555566/14567 20896 30293https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/156/149?format=asciidefaultJ/AJ/156/149/table1Observational constraints and parametersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
