Statistically Optimal Modeling of Flat Eclipses and Exoplanet Transitions. The "Wall-Supported Polynomial" (WSP) Algoritms
Kateryna D. Andrych, Ivan L. Andronov, Lidia L. Chinarova
The methods for determination of the characteristics of the extrema are discussed with an application to irregularly spaced data, which are characteristic for photometrical observa…
Effects of the Mass Transfer and Presence of the Third Components in Close Binary Stellar Systems
Dmytro E. Tvardovskyi, Vladyslava I. Marsakova, Ivan L. Andronov
In our research, we have studied 6 close binary stellar systems which are eclipsing variables of Lyrae and W Ursae Majoris types of variability. We have studied their O-C curve…
Cosmic screening of the gravitational interaction
Maxim Eingorn, Claus Kiefer, Alexander Zhuk
We study a universe filled with cold dark matter in the form of discrete inhomogeneities (e.g., galaxies) and dark energy in the form of a continuous perfect fluid. We develop a fi…
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…
Barium abundance in the central part of the dSph Fornax galaxy
S. M. Andrievsky, S. A. Korotin, V. Hill +1
We revisited barium abundance in a sample of giant stars in the dwarf spheroidal Fornax galaxy. Non-local thermodynamic equilibrium (NLTE) synthesis was used to derive the barium a…
Bending mode and thermal expansion of graphene
Viktor N. Bondarev, Vadym Adamyan, Volodymyr V. Zavalniuk
Proceeding from the model of a two-dimensional elastic continuum, we describe the characteristic features of thermal expansion of graphene using an approach that goes beyond the qu…
