Analysis of pulsating variable stars using the visibility graph algorithm. [PDF]
PLoS One, 2021 We study the light curves of pulsating variable stars using a complex network approach to build visibility graphs. We consider various types of variables stars (e.g., Cepheids, δ Scuti, RR Lyrae), build two types of graphs (the normal visibility graph ...

Observational Properties of 155 β Cephei Pulsating Variable Stars [PDF]
The Astrophysical Journal Supplement Seriesβ Cephei pulsating variable (BCEP) stars are the most massive pulsating variable stars in the main sequence, exhibiting both p- and g-mode pulsations. In this study, we identified 155 BCEP stars or candidates using data from TESS and Gaia, of which 83 ...

The Onset of Chaos in Pulsating Variable Stars
Odessa Astronomical Publications, 2010 Random changes in pulsation period occur in cool pulsating Mira variables, Type A, B, and C semiregular variables, RV Tauri variables, and in most classical Cepheids.

Pulsating variable stars in the Magellanic Clouds [PDF]
Proceedings of the International Astronomical Union, 2008 Pulsating variable stars can be powerful tools to study the structure, formation and evolution of galaxies. I discuss the role that the Magellanic Clouds' pulsating variables play in our understanding of the whole Magellanic System, in light of results ...

Observational Properties of 155 O- and B-type Massive Pulsating Stars [PDF]
The Astrophysical Journal Supplement Series, 2023 O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from various sky surveys provides an unprecedented opportunity to search for and ...
