Bayesian analysis of interiors of HD 219134b, Kepler-10b, Kepler-93b, CoRoT-7b, 55 Cnc e, and HD 97658b using stellar abundance proxies [PDF]

, 2016
Using a generalized Bayesian inference method, we aim to explore the possible interior structures of six selected exoplanets for which planetary mass and radius measurements are available in addition to stellar host abundances: HD~219134b, Kepler-10b ...

Structure and evolution of super-Earth to super-Jupiter exoplanets: I. heavy element enrichment in the interior [PDF]

, 2008
We examine the uncertainties in current planetary models and we quantify their impact on the planet cooling histories and mass-radius relationships.

Highlight Advances in Planetary Physics in the Solar System: In Situ Detection Over the Past 20 Years

Space: Science & Technology, 2023
Planetary science is the science of studying planets, moons, and planetary systems. The scale of the research objects ranges from small meteoroids to large gas giant planets, and the research purpose is to determine their composition, dynamics, formation,

On the Terminal Rotation Rates of Giant Planets [PDF]

, 2018
Within the general framework of core-nucleated accretion theory of giant planet formation, the conglomeration of massive gaseous envelopes is facilitated by a transient period of rapid accumulation of nebular material.

Predicting phase transition pressure in solids: a semiclassical possibility

, 1999
This is a short review of the physical ideas,algorithm for calculations and some results of a semiclassical theory of the behaviour of materials under high pressure,proposed by P.Savic and R.Kasanin.The theory has found applications from DAC experiments ...

Kepler constraints on planets near hot Jupiters [PDF]

, 2012
We present the results of a search for planetary companions orbiting near hot Jupiter planet candidates (Jupiter-size candidates with orbital periods near 3 d) identified in the Kepler data through its sixth quarter of science operations.

Probing the Rock Mass Fraction and Transport Efficiency inside Uranus Using 40Ar Measurements

The Planetary Science Journal
The bulk of Uranus consists of a rock–ice core, but the relative proportions of rock and ice are unknown. Radioactive decay of potassium in the silicates produces ^40 Ar.

Solar-like oscillations in a massive star [PDF]

, 2009
Seismology of stars provides insight into the physical mechanisms taking place in their interior, with modes of oscillation probing different layers. Low-amplitude acoustic oscillations excited by turbulent convection were detected four decades ago in ...

Tidally-forced turbulence in planetary interiors [PDF]

Geophysical Journal International, 2016
The turbulence generated in the liquid metal cores and subsurface oceans of planetary bodies may be due to the role of mechanical forcing through precession/nutation, libration, tidal forcing and collisions. Here, we model the response of an enclosed constant density fluid to tidal forcing by combining laboratory equatorial velocity measurements with ...

Quantitative Sensitivity Assessment of Martian Geodetic Parameters to Interior Model: Implications for Joint Inversion

The Astrophysical Journal
Geodetic parameters are widely used in joint inversion to infer the interior structure of planets. However, joint inversion often involves complex parameterizations that may be computationally costly.
