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…
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…
