Observational Properties of 155 β Cephei Pulsating Variable Stars [PDF]

open access: goldThe 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]

open access: diamondEPJ 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.

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 ...

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

open access: diamondOdessa 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.

Maia variables and other anomalies among pulsating stars [PDF]

open access: greenFrontiers in Astronomy and Space Sciences, 2023
High-precision photometry from TESS has revealed over 500 stars, located between the δ Scuti and β Cephei instability strips, which pulsate with high frequencies. Models do not predict high pulsation frequencies in these stars. These anomalous variables may be identified with the historical “Maia” variables. From the projected rotational velocities, it

Pulsating stars -- plethora of variables and observational tasks [PDF]

open access: green, 2014
Developments of this far-reaching research field are summarized from an observational point of view, mentioning important and interesting phenomena discovered recently by photometry of stellar oscillations of any kind. A special emphasis is laid on Cepheids and RR Lyrae type variables.

Selected new results on pulsating variable stars [PDF]

open access: green, 2019
Recent progress in the studies of pulsating variable stars is summarized from an observational point of view. A number of unexpected phenomena have been revealed in the case of pulsators in the classical instability strip. These discoveries -- lacking theoretical explanation yet -- make pulsating stars more valuable objects for astrophysics than before.
