Analysis of pulsating variable stars using the visibility graph algorithm [PDF]

open access: yesPLoS 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 ...

THE ONSET OF CHAOS IN PULSATING VARIABLE STARS

open access: yesOdessa 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.

An Observer's View on the Future of Asteroseismology [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Scientific research is a continuous process, and the speed of future progress can be estimated by the pace of finding explanations for previous research questions. In this observer's based view of stellar pulsation and asteroseismology, we start with the

Pulsating variable stars in the Magellanic Clouds [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
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 ...

Pulsating variable stars and large spectroscopic surveys [PDF]

open access: yesEPJ Web of Conferences, 2017
In the past decade, the research of pulsating variable stars has taken a giant leap forward thanks to the photometric measurements provided by space missions like Most, CoRoT, Kepler/K2, and Brite.

Pulsating stars in ω Centauri. Near-IR properties and period-luminosity relations [PDF]

open access: yesEPJ Web of Conferences, 2017
ω Centauri (NGC 5139) contains many variable stars of different types, including the pulsating type II Cepheids, RR Lyrae and SX Phoenicis stars. We carried out a deep, wide-field, near-infrared (IR) variability survey of ω Cen, using the VISTA telescope.

Observational Properties of 155 β Cephei Pulsating Variable Stars

open access: yesThe Astrophysical Journal Supplement Series
β 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 ...

MULTI-COMPONENT VARIABILITY OF PULSATING VARIABLE STARS OF RV TAURI TYPE

open access: yesOdessa Astronomical Publications, 2020
For the group of pulsating variable stars with multi-component variability – which are currently classified as the RV Tau-type stars – the classification based on complexity of the periodograms is discussed.

Observational Properties of 155 O- and B-type Massive Pulsating Stars

open access: yesThe 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 ...
