Pulsating and Nonpulsating Components of Detached Eclipsing Binaries in the δ Scuti Instability Strip

open access: yesThe Astronomical Journal
Pulsating detached eclipsing binary systems are crucial for studying the internal structure of oscillating stars. These systems are advantageous because binary effects on pulsations are minimal, allowing for more accurate determinations of fundamental ...

KIC 5623923: A Faint Eclipsing Binary Consisting of δ Scuti Pulsations

open access: yesThe Astrophysical Journal
In 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 ...

A Systematic Search for New δ Scuti and γ Doradus Stars Using TESS Data

open access: yes
Focusing on the discovery of new δ Scuti and γ Doradus stars, we analyzed the Transiting Exoplanet Survey Satellite (TESS) light curves for 193,940 A-F stars selected from four legacy catalogs—the Henry Draper Catalogue (HD), the ...

Nonradial pulsations of delta Scuti stars [PDF]

open access: yes, 1986
An improved stellar model with a detailed composition structure is used to look at the nonradial behavior of a star near the region in the H-R diagram where the delta Scuti variables are found.

KIC 8840638: A Newly Discovered Eclipsing Binary with δ Scuti–Type Oscillations

open access: yesThe Astrophysical Journal
In 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 ...

Precise Parameter Determination of the Open Cluster NGC 1647 via Asteroseismology of p-mode Pulsators

open access: yesThe Astrophysical Journal
Asteroseismology of member pulsators provides a robust physical constraint on cluster parameters by linking internal stellar structures to the global properties of the host cluster.

Monoperiodic $\delta$ Scuti star UY Cam: an analogue of SX Phe and RR Lyr-type variables

open access: yes, 2003
We present the results of a four-year photometric study of the high-amplitude $\delta$ Scuti star (HADS) UY Camelopardalis. Analyses on the available data from 1985 to 2003 show that UY Cam is monoperiodic. Fourier solutions for individual data sets do not reveal period changes in the star. Although forced parabolic fits to the $O-C$ residuals indicate

The Rotation Properties of δ Sct and γ Dor Stars

open access: yesThe Astrophysical Journal
Based on the LAMOST spectroscopy and TESS time-series photometry, we have obtained a main-sequence star sample of δ Scuti and γ Doradus stars. The sample includes 1534 δ Sct stars, 367 γ Dor stars, 1703 δ Sct ∣ γ Dor stars, 270 γ Dor ∣ δ Sct stars, along
