Second-generation protoplanetary discs around evolved binaries: a high-resolution polarimetric view with SPHERE/IRDIS
Kateryna Andrych, Devika Kamath, Jacques Kluska +3
Binary post-asymptotic giant branch (post-AGB) stars are products of a poorly understood binary interaction process that occurs during the AGB phase. These systems comprise of a po…
Transition disc nature of post-AGB binary systems confirmed by mid-infrared interferometry
A. Corporaal, J. Kluska, H. Van Winckel +4
Many properties of circumbinary discs around evolved post-asymptotic giant branch (post-AGB) binary systems are similar to those of protoplanetary discs around young stars. The def…
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…
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…
MAVKA: Software for Statistically Optimal Determination of Extrema
Kateryna D. Andrych, Ivan L. Andronov
We introduce the program MAVKA for determination of characteristics of extrema using observations in the adjacent data intervals, with intended applications to variable stars, but…
