Weak field limit of higher dimensional massive Brans-Dicke gravity: Observational constraints
Ozgur Akarsu, Alexey Chopovsky, Valerii Shulga +2
We consider higher-dimensional massive Brans-Dicke theory with Ricci-flat internal space. The background model is perturbed by a massive gravitating source which is pressureless in…
Black branes and black strings in the astrophysical and cosmological context
Ozgur Akarsu, Alexey Chopovsky, Alexander Zhuk
We consider Kaluza-Klein models where internal spaces are compact flat or curved Einstein spaces. This background is perturbed by a compact gravitating body with the dust-like equa…
Brane world models with bulk perfect fluid and broken 4D Poincare invariance
Ozgur Akarsu, Alexey Chopovsky, Maxim Eingorn +2
We consider 5D brane world models with broken global 4D Poincar\a'{e} invariance (4D part of the spacetime metric is not conformal to the Minkowski spacetime). The bulk is filled w…
Weak-field limit of Kaluza-Klein models with spherically symmetric static scalar field: observational constraints
Alexander Zhuk, Alexey Chopovsky, Seyed Hossein Fakhr +2
In a multidimensional Kaluza-Klein model with Ricci-flat internal space, we study the gravitational field in the weak-field limit. This field is created by two coupled sources. Fir…
Problematic aspects of Kaluza-Klein excitations in multidimensional models with Einstein internal spaces
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
We consider Kaluza-Klein (KK) models where internal spaces are compact Einstein spaces. These spaces are stabilized by background matter (e.g., monopole form-fields). We perturb th…
Kaluza-Klein multidimensional models with Ricci-flat internal spaces: the absence of the KK particles
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
In this paper we consider a multidimensional Kaluza-Klein (KK) model with a Ricci-flat internal space, e.g., a Calabi-Yau manifold. We perturb this background metrics by a system o…
Many-body problem in Kaluza-Klein models with toroidal compactification
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
In this paper, we consider a system of gravitating bodies in Kaluza-Klein models with toroidal compactification of extra dimensions. To simulate the astrophysical objects (e.g., ou…
Many-body problem in Kaluza-Klein models: theory and observational consequences
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
We consider a system of gravitating bodies in Kaluza-Klein models with toroidal compactification of extra dimensions. To simulate the astrophysical objects (e.g., our Sun and pulsa…
Exact and asymptotic black branes with spherical compactification
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
In the six-dimensional Kaluza-Klein model with the multidimensional cosmological constant , we obtain the black brane with spherical compactification of the internal space. Th…
Weak-field limit of Kaluza-Klein models with spherical compactification: experimental constraints
Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
We investigate the classical gravitational tests for the six-dimensional Kaluza-Klein model with spherical (of a radius ) compactification of the internal space. The model conta…

Alexey Chopovsky, Maxim Eingorn, Alexander Zhuk
We investigate classical gravitational tests for the Kaluza-Klein model with spherical compactification of the internal two-dimensional space. In the case of the absence of a multi…
