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 possesses a central core of 14 – 18 Earth masses of heavier elements, a result that supports core accretion as standard model for the formation of hydrogen-rich giant planets. Our nominal model has about 2 Earth masses of...

The equilibrium of dense plasma in a gravity field and problem of a gravity-induced electric polarization in this matter are discussed. The calculation for metals performed before shows that both-the gravity-induced compressive strain and the gravity-induced electric field-are inversely proportional to their Young moduli. The calculation for high dense plasma, where Young modulus is equal to ze...

The aim of this paper is to investigate the influences of rotation, magnetic field, initial stress, and gravity field on Rayleigh waves in a homogeneous orthotropic elastic medium. The government equations is solved by Lame’s potential and obtained the frequency equation which determines the velocity of Rayleigh waves, including rotation, initial stress, gravity field, and magnetic field, in a ...

We consider the Kehagias-Sfetsos (KS) solution in the Ho!ava-Lifshitz gravity that is the analog of the general relativistic Schwarzschild black hole. In the weak-field and slow-motion approximation, we, first, work out the correction to the third Kepler law of a test particle induced by such a solution. Then, we compare it to the phenomenologically determined orbital period of the transiting e...

39 This paper describes the computation and analysis of the Earth's short-scale gravity field 40 through high-resolution gravity forward modelling using the Shuttle Radar Topography 41 Mission (SRTM) global topography model. We use the established residual terrain modelling 42 technique along with advanced computational resources and massive parallelisation to 43 convert the high-pass filtered ...

This is a semi-technical presentation of the succession of events that led Einstein to formulate his theory of general relativity. We present an overview of the field of relativistic astrophysics and motivate the study of compact objects (such as neutrons stars and black holes) as strong-field gravity probes for testing possible modifications to general relativity. 1 A PANORAMA OF PHYSICS BEFOR...
