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 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 ...

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.

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 Coma Berenices dwarf spheroidal galaxy [PDF]

The Astrophysical Journal, 2009
We present B, V, I time-series photometry of the Coma Berenices dwarf spheroidal galaxy, a faint Milky Way satellite, recently discovered by the Sloan Digital Sky Survey.

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

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

EPJ 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.

Pulsating variable stars in the Magellanic Clouds [PDF]

Proceedings 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 ...
