R Scuti: Close Alternating Pulsation Periods or Chaos in the RV Tau -- Type Star?
L. S. Kudashkina, I. L. Andronov
Results of analysis of 60010 data photometric observations from the AAVSO international database are presented, which span 120 years of monitoring. The periodogram analysis shows t…
Preliminary analysis of periodogram shapes and their classification
L. S. Kudashkina
A periodogram analysis of 47 stars noted in GCVS as RV-type stars was carried out. The research methods applied here to RV-type stars have previously been applied to long-period va…
Semiregular variable stars
L. S. Kudashkina
The studies of semiregular variables of stars by different authors are considered, and the main theoretical and observational problems associated with these stars are reviewed. The…
Atlas of the Light Curves and Phase Plane Portraits of Selected Long-Period Variables
L. S. Kudashkina, I. L. Andronov
For a group of the Mira-type stars, semi-regular variables and some RV Tau - type stars the limit cycles were computed and plotted using the phase plane diagrams. As generalized co…
Phase Plane Analysis of the Photometrical Variations of Long-Period Variables
Larisa S. Kudashkina, Ivan L. Andronov
Using the phase plane diagrams, the phase light curves of a group of the Mira-type stars and semi-regular variables are analyzed. As generalized coordinates x and , we hav…
Instabilities in Interacting Binary Stars
Ivan L. Andronov, K. D. Andrych, K. A. Antoniuk +43
The types of instability in the interacting binary stars are reviewed. The project "Inter-Longitude Astronomy" is a series of smaller projects on concrete stars or groups of stars.…
The mean light curves of the Mira-type stars in the H- and K-bands
L. S. Kudashkina
For nine Mira-type stars (o Cet, R Leo, S Car, U Her, X Oph, R Aql, RR Aql, S Ori, S Scl,) and one semi-regular star (L2 Pup), the mean light curves have been obtained. The initial…
The model parameters of the mean light curves of the variable red giant stars in the near infrared colour-bands and compare them with the visual mean light curves
L. S. Kudashkina
The observational data of the near infrared bands (H and K) have been used for the modeling mean light curves. Also the visual observational data have been fitted the same. The inf…
Statistical Studies of Long - Period Variable Stars in Odessa
Larisa S. Kudashkina, Ivan L. Andronov, Vladislava I. Marsakova +1
The studies of pulsating variable stars are traditional subjects of astronomers in Odessa. In the last half of the 20th century, the studies of the physical variable stars were the…
Photometric Behavior of Five Long-Period Pulsating Stars
Larisa S. Kudashkina, Ivan L. Andronov, Lidia V. Grenishena
The variation of average brightness during the time and the variation of the amplitude of the Mira-type stars T Cep, X CrB, U UMi, U Cyg, BG Cyg is studied. For the research, the o…
