Eclipsing binary stars with a δ Scuti component [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
Eclipsing binaries with a $\delta$ Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of 6 primary $\delta$ Sct components in eclipsing binaries has been ...

TESS Eclipsing Binary Stars. I. Short-cadence Observations of 4584 Eclipsing Binaries in Sectors 1–26 [PDF]

Astrophysical Journal Supplement Series, 2021
In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary candidates, detection of hitherto unknown eclipsing systems ...

Automatic classification of eclipsing binary stars using deep learning methods [PDF]

Astronomy and Computing, 2021
In the last couple of decades, tremendous progress has been achieved in developing robotic telescopes and, as a result, sky surveys (both terrestrial and space) have become the source of a substantial amount of new observational data.

The surface brightness–colour relations based on eclipsing binary stars and calibrated with Gaia EDR3 [PDF]

Astronomy & Astrophysics, 2021
Aims. The surface brightness–colour relation (SBCR) is a basic tool for establishing precise and accurate distances within the Local Group. Detached eclipsing binary stars with accurately determined radii and trigonometric parallaxes allow calibration of

New Pulsating Stars Detected in EA-type Eclipsing-binary Systems Based on TESS Data [PDF]

Astrophysical Journal Supplement Series, 2022
Pulsating stars in eclipsing binaries are very important for understanding the structure of stellar interiors through asteroseismology because their absolute parameters such as their masses and radii can be determined with high precision based on ...

Eclipsing Systems with Pulsating Components (Types β Cep, δ Sct, γ Dor or Red Giant) in the Era of High-Accuracy Space Data

Galaxies, 2021
Eclipsing systems are essential objects for understanding the properties of stars and stellar systems. Eclipsing systems with pulsating components are furthermore advantageous because they provide accurate constraints on the component properties, as well
