The MAGIC project. III. Radial and azimuthal Galactic abundance gradients using classical Cepheids
V. Kovtyukh, B. Lemasle, G. Bono +7
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chem…
Astroinformatics: Statistically Optimal Approximations of Near-Extremal Parts with Application to Variable Stars
Ivan L. Andronov, Kateryna D. Andrych, Lidia L. Chinarova +1
The software MAVKA is described, which was elaborated for statistically optimal determination of the characteristics of the extrema of 1000+ variable stars of different types, main…
Poorly Studied Eclipsing Binaries in the Field of DO Dra: V0455 Dra and V0454 Dra
Yonggi Kim, Ivan L. Andronov, Kateryna D. Andrych +3
We report an analysis of two poorly studied systems GSC 04396-00605 and GSC 04395-00485, which were recently named as V0455 Dra and V0454 Dra, respectively. For two eclipsing stars…
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
Kateryna D. Andrych, Ivan L. Andronov, Lidia L. Chinarova
Advanced MAVKA software for the approximation of extrema observations is used to analyze the variability of the brightness of pulsating and eclipsing stars, but may be useful in an…
Multi-Algorithm Analysis Of The Semi-Regular Variable DY Per, The Prototype Of The Class Of Cool RCrB Variables
Ivan L. Andronov, Kateryna D. Andrych, Lidia L. Chinarova
Multiple algorithms of time series analysis are briefly reviewed and partially illustrated by application to the visual observations of the semi-regular variable DY Per from the AF…
Variable Stars: A Net of Complementary Methods for Time Series Analysis. Application to RY UMa
Ivan L. Andronov, Lidia L. Chinarova
The expert system for time series analysis of irregularly spaced signals is reviewed. It consists of a number of complementary algorithms and programs, which may be effective for d…
