Chemical abundances of solar neighborhood RR Lyrae stars
E. Pancino, N. Britavskiy, D. Romano +3
We have analysed a sample of 18 RR Lyrae stars (17 fundamental-mode - RRab - and one first overtone - RRc) and three Population II Cepheids (two BL Her stars and one W Vir star), f…
Determination of Size of the Emitting Region in Eclipsing Cataclysmic Variable Stars
Ivan L. Andronov, Kateryna D. Andrych
The dependencies of the phase of eclipse of the white dwarf's centre and the durations of the ascending and descending branches of the light curve on the binary system's parameters…
New insights on Ba over-abundance in open clusters. Evidence for the intermediate neutron-capture process at play?
T. Mishenina, M. Pignatari, G. Carraro +6
Recently an increasing number of studies were devoted to measure the abundances of neutron-capture elements heavier than iron in stars belonging to Galactic Open Clusters (OCs). OC…
Lattice Universe: examples and problems
Maxim Brilenkov, Maxim Eingorn, Alexander Zhuk
We consider lattice Universes with spatial topologies , and . In the Newtonian limit of General Relativity, we so…
The chemical composition of red giants in 47 Tucanae I: Fundamental parameters and chemical abundance patterns
A. O. Thygesen, L. Sbordone, S. Andrievsky +9
Context: The study of chemical abundance patterns in globular clusters is of key importance to constrain the different candidates for intra-cluster pollution of light elements. Aim…
Oxygen abundance distribution in Galactic disc
S. A. Korotin, S. M. Andrievsky, R. E. Luck +3
We have performed a NLTE analysis of the infrared oxygen triplet for a large number of cepheid spectra obtained with the Hobby-Eberly telescope. These data were combined with our p…
Transverse spin and momentum in two-wave interference
Aleksandr Y. Bekshaev, Konstantin Y. Bliokh, Franco Nori
We analyze the interference field formed by two electromagnetic plane waves (with the same frequency but different wave vectors), and find that such field reveals a rich and highly…
Zero average values of cosmological perturbations as an indispensable condition for the theory and simulations
Maxim Eingorn, Maxim Brilenkov, Branislav Vlahovic
We point out a weak side of the commonly used determination of scalar cosmological perturbations lying in the fact that their average values can be nonzero for some matter distribu…
The critical compressibility factor value: associative fluids and liquid alkali metals
Vladimir Kulinskii
We show how to obtain the critical compressibility factor for simple and associative Lennard-Jones fluids using the critical characteristics of the Ising model on different l…
Orientation of galaxies in structures
Elena Panko, Paulina Piwowarska, Jolanta Godlowska +2
The investigation of the orientation of galaxies is a standard test concerning to scenarios of galaxy formation, because different theories of galaxy formation make various predict…
Linear programming over exponent pairs
Andrew V. Lelechenko
We consider the problem of the computation of over the set of exponent pairs under linear constraints for a certain class of objective functions . An effec…
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…
The Origin of the Young Pulsar PSR J0826+2637 and Its Possible Former Companion HIP 13962
N. Tetzlaff, B. Dincel, R. Neuhaeuser +1
We aim to identify the birth place of the young pulsar PSR J0826+2637 in order to determine its kinematic age and give constraints on its radial and spatial (kick) velocity. Since…
gravity: scalar perturbations in the late Universe
Maxim Eingorn, Jan Novák, Alexander Zhuk
In this paper we study scalar perturbations of the metric for nonlinear models. We consider the Universe at the late stage of its evolution and deep inside the cell of unifo…
