Period–Luminosity Relations for Double-mode δ Sct Stars
The Astrophysical JournalPrevious studies of the period–luminosity relations (PLRs) of Delta Scuti ( δ Sct) stars have focused on those with a single pulsation mode. However, for δ Sct stars with many different pulsation modes, classifying a single mode is difficult.

, 2010 The sixth part of the OGLE-III catalog of Variable Stars presents Sct pulsators in the Large Magellanic Cloud. Altogether 2786 variable stars were found and amongst them 92 are multi-mode objects, including 67 stars pulsating in the fundamental mode and the first overtone (F/1O), nine double-mode pulsators with various combinations of the first three

The Astrophysical Journalδ Scuti stars in binary or multiple systems serve as crucial probes for studying stellar pulsation and evolution. However, many such systems are not ideal for asteroseismology due to uncertainties in mass transfer with close companions and the challenges

Discovery of 79 δ Scuti Stars in NGC 3532 Suggests a Decrease of Pulsator Occurrence with Age
The Astrophysical JournalMany A–F type stars do not display δ Scuti pulsations, despite being located within the instability strip. Open clusters provide a unique opportunity to study δ Scuti pulsations among coeval populations with uniform chemical composition. Here we use data

KIC 5623923: A Faint Eclipsing Binary Consisting of δ Scuti Pulsations
The Astrophysical JournalIn this paper, we present a detailed analysis of the light variation of KIC 5623923 using high-precision time-series data from the Kepler mission. The analysis reveals this target is an eclipsing binary system with δ Scuti-type pulsations from the ...

KIC 8840638: A Newly Discovered Eclipsing Binary with δ Scuti–Type Oscillations
The Astrophysical JournalIn this paper, we analyze the light variation of KIC 8840638 using high-precision time-series data from the Kepler mission. The analysis reveals that this target is a new detached eclipsing binary system with a δ Scuti component, rather than a single δ ...
