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 ...

Pulsating variable stars and large spectroscopic surveys [PDF]
EPJ 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.

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 ...

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.

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

Variability and pulsations in the Be star 66 Ophiuchi [PDF]
Astronomy & Astrophysics, 2002 Oph is a Be star seen under a moderate inclination angle that shows strong variability from UV to IR wavelengths. A concise review of long-term variability history is given. High resolution, high S /N spectroscopic observations obtained in 1997, 1998 and 2001 and spectropolarimetric observations obtained in 2000 are presented.

Investigating Stellar Variability in the Open Cluster Region NGC 381
The Astronomical Journal, 2023 We study variable stars in the field of the open cluster NGC 381 using photometric data observed over 27 nights and identify a total of 57 variable stars, six of which are member stars. The variable stars are classified based on their periods, amplitudes,

A Catalog of New Slowly Pulsating B-type Stars
The Astrophysical Journal Supplement Series, 2023 This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have found 286 new slowly pulsating B-type (SPB) stars and 21 candidates.
