Discovery and characterisation of long-period eclipsing binary stars from Kepler K2 campaigns 1, 2 and 3 [PDF]

A&A 616, A38 (2018), 2018
The Kepler K2 mission now makes it possible to find and study a wider variety of eclipsing binary stars than has been possible to-date, particularly long-period systems with narrow eclipses. Our aim is to characterise eclipsing binary stars observed by the Kepler K2 mission with orbital periods longer than $P\approx 5.5$ days.

Kepler Eclipsing Binary Stars. V. Identification of 31 Eclipsing Binaries in the K2 Engineering Data-set [PDF]

, 2014
Over 2500 eclipsing binaries were identified and characterized from the ultra-precise photometric data provided by the Kepler space telescope. Kepler is now beginning its second mission, K2, which is proving to again provide ultra-precise photometry for a large sample of eclipsing binary stars.

Eclipsing binary stars with a $δ$ Scuti component [PDF]

, 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 performed.

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 ...

Variability of Young Massive Stars in the Galactic Super Star Cluster Westerlund 1 [PDF]

Astron.J.133:2696-2708,2007, 2007
This paper presents the first optical variability study of the Westerlund 1 super star cluster in search of massive eclipsing binary systems. A total of 129 new variable stars have been identified, including the discovery of 4 eclipsing binaries that are cluster members, 1 additional candidate, 8 field binaries, 19 field delta Scuti stars, 3 field W ...

ELLC - a fast, flexible light curve model for detached eclipsing binary stars and transiting exoplanets [PDF]

, 2016
Very high quality light curves are now available for thousands of detached eclipsing binary stars and transiting exoplanet systems as a result of surveys for transiting exoplanets and other large-scale photometric surveys.

Eclipsing binary stars in the era of massive surveys First results and future prospects [PDF]

EPJ Web of Conferences, 2017
Our thinking about eclipsing binary stars has undergone a tremendous change in the last decade. Eclipsing binary stars are one of nature’s best laboratories for determining the fundamental physical properties of stars and thus for testing the predictions

Asteroseismology of Eclipsing Binary Stars in the Kepler Era [PDF]

, 2014
Eclipsing binary stars have long served as benchmark systems to measure fundamental stellar properties. In the past few decades, asteroseismology - the study of stellar pulsations - has emerged as a new powerful tool to study the structure and evolution ...

Eclipsing Binary Stars in the OGLE-III Galactic Disk Fields [PDF]

arXiv, 2013
We present the analysis of 11 589 eclipsing binary stars identified in twenty-one OGLE-III Galactic disk fields toward constellations of Carina, Centaurus, and Musca. All eclipsing binaries but 402 objects are new discoveries. The binaries have out-of-eclipse brightness between I=12.5 mag and I=21 mag.

ECLIPSING BINARY STARS AS BENCHMARKS FOR TRIGONOMETRIC PARALLAXES IN THE GAIA ERA [PDF]

, 2016
We present fits to the broadband photometric spectral energy distributions (SEDs) of 158 eclipsing binaries (EBs) in the Tycho-2 catalog. These EBs were selected because they have highly precise stellar radii, effective temperatures, and in many cases ...
