Abstract The aim of this paper is to introduce the software and astronomical web-services developed in frame of the Ukraine Virtual Observatory (UkrVO) and VIrtual Roentgen and Gamma Observatory (VIRGO) to the broad astronomical community. We report briefly on such web-services as the public databases “Sky Maps” of X-ray observations by XMM-Newton, the Earth Orbital Parameters for International Earth Rotation System, and the UkrVO Joint Digitized Archive of astroplates. We refer to such software as the “Multi-Column View”, “Variable Stars Calculator”, “FrameSmooth” for variable star’s research and “Collection Light Technology” (CoLiTec) software for search and discovery of new Solar System bodies.read more

MAVKA: Program of Statistically Optimal Determination of Phenomenological Parameters of Extrema. Parabolic Spline Algorithm And Analysis of Variability of The Semi-Regular Star Z UMa
TL;DR: In this article, a new algorithm using a parabolic (quadratic) spline is proposed to analyze the variability of the brightness of pulsating and eclipsing stars, but may be useful in analyzing signals of any nature.

Period Variations and Possible Third Components in the Eclipsing Binaries AH Tauri and ZZ Cassiopeiae
TL;DR: In this article, the authors investigated two variable stars: AH Tau and ZZ Cas, which are eclipsing binary stars of W Ursae Majoria and Lyrae types.

Third Components With Elliptical Orbits in the Eclipsing Binaries
TL;DR: Andrych et al. as mentioned in this paper studied 9 eclipsing binary stars: AR Lac, U CrB, S Equ, SU Boo, VV UMa, WW Gem, YY Eri, V0404 Lyr, HP Aur.

Period Variations and Possible Third Components in the Eclipsing Binaries AH Tauri and ZZ Cassiopeiae
TL;DR: In this paper, the authors investigated two variable stars AH Tau and ZZ Cas and found that the changes of the period are cyclic caused by the presence of a hypothetical third component (either a small star or a large planet).

TL;DR: In the lead-up to the Square Kilometre Array (SKA) project, several next-generation radio telescopes and upgrades are already being built around the world as discussed by the authors, and a radio continuum survey is being planned on each of them with the primary science objective of understanding the formation and evolution of galaxies over cosmic time, and the cosmological parameters and large-scale structures which drive it.

The XPM Catalogue: absolute proper motions of 280 million stars
TL;DR: In this paper, the absolute proper motions of about 280 million stars distributed all over the sky, except a small region near the Galactic Centre, in the magnitude range 12 < B < 19 mag were derived from the 2MASS Point Sources and USNO-A2.0 catalogues.
