Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
effective theory of inflation new shapes of non-Gaussianity
2010/11/16
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
An exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the $\Lambda$CDM model
exact cosmological solution Scalar-Tensor Gravity theory compatible $\Lambda$CDM model
2010/11/15
consider the massive Scalar-Tensor theory in the Jordan frame F() = K22,Z() = 1, and U() = (1/2)m22, F() corresponds to a constant Brans-Dicke parameter !BD = 1/4K2. The constaint of the solar s...
A Unified Theory for the Effects of Stellar Perturbations and Galactic Tides on Oort Cloud Comets
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
We examine the effects of passing field stars on the angular momentum of a nearly radial orbit of an Oort cloud comet bound to the Sun. We derive the probability density function (PDF) of the change i...
Gravitation Field Dynamics in Jeans Theory
Time equations Jeans theory Bogolyubov reduced description method perturbation types

Closed system of time equations for nonrelativistic gravitation field and hydrodynamic medium was obtained by taking into account binary correlations of the field, which is the generalization of Jeans...
