Asymptotic latent solitons, black strings and black branes in f(R)-gravity
Maxim Eingorn, Alexander Zhuk
We investigate nonlinear f(R) theories in the Kaluza-Klein models with toroidal compactification of extra dimensions. A point-like matter source has the dust-like equation of state…
Non-relativistic limit of Randall-Sundrum model: solutions, applications and constraints
Maxim Eingorn, Alexandra Kudinova, Alexander Zhuk
In the Randall-Sundrum model with one brane, we found the approximate and exact solutions for gravitational potentials and accelerations of test bodies in these potentials for diff…
Orbital rotation without orbital angular momentum: mechanical action of the spin part of the internal energy flow
O. V. Angelsky, A. Ya. Bekshaev, P. P. Maksimyak +3
It is known that internal energy flow in a light beam can be divided into the orbital flow, associated with the macroscopic energy redistribution within the beam, and the spin flow…
Galactic restrictions on iron production by various Types of supernovae
I. A. Acharova, Yu. N. Mishurov, V. V. Kovtyukh
We propose a statistical method for decomposition of contributions to iron production from various sources: supernovae Type II and the subpopulations of supernovae Type Ia -- promp…
Polarization-dependent transformation of a paraxial beam upon reflection and refraction: a real-space approach
Aleksandr Bekshaev
We analyze the paraxial beam transformation upon reflection and refraction at a plane boundary. In contrast to the usual approach dealing with the beam angular spectrum, we apply t…
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…
Overlapping abundance gradients and azimuthal gradients related to the spiral structure of the Galaxy
J. R. D. Lepine, P. Cruz, S. Scarano +6
The connection between some features of the metallicity gradient in the Galactic disk, best revealed by Open Clusters and Cepheids, and the spiral structure, is explored. The step-…
Role of Azimuthal Energy Flows in the Geometric Spin Hall Effect of Light
Aleksandr Bekshaev
In an oblique section of a paraxial beam with angular momentum, the beam center of gravity (CG) is shifted with respect to its position in the normal cross section. We relate this…
The Distribution of the Elements in the Galactic Disk II. Azimuthal and Radial Variation in Abundances from Cepheids
R. E. Luck, S. M. Andrievsky, V. V. Kovtyukh +2
This paper reports on the spectroscopic investigation of 101 Cepheids in the Carina region. These Cepheids extend previous samples by about 35% in number and increase the amount of…
Multi-site, multi-year monitoring of the oscillating Algol-type eclipsing binary CT Her
P. Lampens, A. Strigachev, S. -L. Kim +13
We present the results of a multi-site photometric campaign carried out in 2004-2008 for the Algol-type eclipsing binary system CT Her, the primary component of which shows Delta S…
The Vliegenthart-Lekkerkerker relation. The case of the -fluids
Vladimir L. Kulinskii
The Vliegenthart-Lekkerkerker relation for the second virial coefficient value at the critical temperature found in [G. A. Vliegenthart and H. N. W. Lekkerkerker, J. Chem. Phys. \t…
The NLTE Barium Abundance in Dwarf Stars in the Metallicity Range of -1 < [Fe/H] < +0.3
S. Korotin, T. Mishenina, T. Gorbaneva +1
We present the results of determination of the barium abundance considering the non-LTE (NLTE) effects in 172 dwarf stars in the metallicity range of -1< [Fe/H] <+0.3, assigned to…
NLTE strontium abundance in a sample of extremely metal poor stars and the Sr/Ba ratio in the early Galaxy
S. M. Andrievsky, F. Spite, S. A. Korotin +5
Heavy element abundances in extremely metal-poor stars provide strong constraints on the processes of forming these elements in the first stars. We attempt to determine precise abu…
Weak-field limit of f(R)-gravity in three and more spatial dimensions
Maxim Eingorn, Alexander Zhuk
We investigate a point-like massive source in non-linear f(R) theories in the case of arbitrary number of spatial dimensions D\geq 3. If D>3 then extra dimensions undergo toroidal…
Spectroscopy of high proper motion stars in the ground--based UV
V. Klochkova, T. Mishenina, S. Korotin +4
Based on high quality spectral data (spectral resolution R>60000) within the wavelength range of 3550-5000 AA we determined main parameters (effective temperature, surface gravity,…
First Stars XIV. Sulfur abundances in extremely metal-poor (EMP) stars
Monique Spite, E. Caffau, S. M. Andrievsky +15
Sulfur is important: the site of its formation is uncertain, and at very low metallicity the trend of [S/Fe] against [Fe/H] is controversial. Below [Fe/H]=-2.0, [S/Fe] remains cons…
Latent solitons, black strings, black branes, and equations of state in Kaluza-Klein models
Maxim Eingorn, Orival R. de Medeiros, Luís C. B. Crispino +1
In Kaluza-Klein models with an arbitrary number of toroidal internal spaces, we investigate soliton solutions which describe the gravitational field of a massive compact object. We…
The unified picture for the classical laws of Batschinski and the rectilinear diameter for molecular fluids
Leonid A. Bulavin, Vladimir L. Kulinskii
The explicit relations between the thermodynamic functions of the Lattice Gas model and the fluid within the framework of approach proposed earlier in [V. L. Kulinskii, J. Phys. Ch…
