To date, two planetary systems have been discovered with close-in, terrestrial-mass planets (. 5−10M⊕). Many more such discoveries are anticipated in the coming years with radial velocity and transit searches. Here we investigate the different mechanisms that could form “hot Earths” and their observable predictions. Models include: 1) in situ accretion; 2) formation at larger orbital distance f...

the asymptotically ads solutions of the einstein gravity with hyperbolic horizons in the presence of so(n(n-1)/2- 1,1) yang-mills fields governed by the non-abelian born-infeld lagrangian are presented. we investigate the properties of these solutions as well as their asymptotic behavior in various dimensions. the properties of these kinds of solutions are like the einstein-yang-mills solutions...

Abstract The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is part of ESA’s Earth Program. satellite carries magnetometers that control the activity magnetorquers for navigation satellite, but are not dedicated as science instruments. However, intrinsic steady states instruments can be corrected by alignment calibration, artificial perturbations, e.g. from currents, removed t...

Gravitational physics of VLBI experiment conducted on September 8, 2002 and dedicated to measure the speed of gravity is treated in the first post-Newtonian approximation. Explicit speed-of-gravity parameterization is introduced to the Einstein equations to single out the retardation effect associated with the finite speed of gravity in the relativistic time delay of light propagating in the gr...

In this paper, a lab-on-chip system dedicated to fungi cultivation in Earth’s gravity and simulated microgravity, being solution that could be used future nanosatellite missions, is shown. For the first time, fully glass structure enabling proper environment for of species—Fusarium culmorum—is presented. Apart from biological validation cultures with use system, tests were carried out under ind...
