V405 Draconis: A Deep Contact Binary with a Tertiary Companion and a Quadruple System Candidate
Maksym Yu. Pyatnytskyy, Ivan L. Andronov
We continued our analysis of the O-C diagram of the EW-type eclipsing binary V405 Dra using recently available data. We refined the orbital parameters of the third body responsible…
Physics. Tasks With Solutions
Lidiia L. Chinarova, Ivan L. Andronov, Nina V. Savchuk +2
The study guide (textbook) is part of a set of materials designed to support high-quality practical training in physics. It includes a collection of tasks for organizing both in-cl…
Determination of Light Curve Parameters of Poorly Studied Eclipsing Variables Using Data from Tess and Other Sky Surveys
Vladyslava I. Marsakova, Ivan L. Andronov, Victoriia O. Borshchenko +6
A group of poorly studied eclipsing variables (the classification of which is marked as uncertain and/or the period of brightness changes is uncertain) has been studied with the us…
Multi-harmonic and special shape/pattern/template approximations of discrete signals with generally irregular arguments
Ivan L. Andronov, Hanna M. Akopian, Vitalii V. Breus +7
The invited review of own algorithms and software (MAVKA and MCV) for the data analysis of astronomical signals - irregularly spaced, multi-periodic multi-harmonic, periodogram ana…
The HADS Star CSS_J102714.3+205943: a Component of a Binary System with an Elliptic Orbit?
Maksym Yu. Pyatnytskyy, Ivan L. Andronov
We analyzed period changes of the high-amplitude Delta Scuti variable star CSS_J102714.3+205943 for about 20 years, utilizing data from the automated sky surveys along with our own…
Spin-period variations in the intermediate polar RX J2133.7+5107
V. Breus, I. L. Andronov, P. Dubovsky +3
We report the results of long-term time series photometry on RX J2133.7+5107 (also known as 1RXS J213344.1+510725) obtained at several observatories. Using data taken during 17 yea…
