Ten eclipsing binaries in the Small Magellanic Cloud: fundamental parameters and Cloud distance [PDF]

, 2003
We present the first results of an observational programme to measure the fundamental parameters of over 100 eclipsing binaries in the Small Magellanic Cloud (SMC).

KEPLER ECLIPSING BINARY STARS. I. CATALOG AND PRINCIPAL CHARACTERIZATION OF 1879 ECLIPSING BINARIES IN THE FIRST DATA RELEASE [PDF]

, 2010
The Kepler space mission is devoted to finding Earth-size planets orbiting other stars in their habitable zones. Its large, 105 deg2 field of view features over 156,000 stars that are observed continuously to detect and characterize planet transits. Yet,

Doppler images of the eclipsing binary ER Vulpeculae [PDF]

, 2014
We present Doppler images of both components of the eclipsing binary system ER Vul, based on the spectra obtained in 2004 November, 2006 September and 2008 November.

Tango of celestial dancers: A sample of detached eclipsing binary systems containing [PDF]

, 2020
Context. Eclipsing binary systems with components that pulsate in gravity modes (g modes) allow for simultaneous and independent constraints of the chemical mixing profiles of stars.

Eclipsing Binary Stars in Nearby Galaxies [PDF]

Astrophysics and Space Science, 2006
We briefly discuss the survey programme we are conducting to detect eclipsing binaries in local group galaxies. Some lightcurves from studies of M31, IC 1613 and NGC 6822 are presented along with details of future work.

Roberts of Lovedale and Eclipsing Binary Stars [PDF]

International Astronomical Union Colloquium, 1988
Alexander William Roberts, a great humanitarian and teacher in South Africa, was also a luminary in the astronomical world. This paper discusses his work on variable stars and touches briefly on his career in other areas. Born and educated in Scotland, Roberts migrated to South Africa in 1883, at age 25, to teach at the Native College at Lovedale.

Phenomenological modeling of the light curves of algol-type eclipsing binary stars [PDF]

, 2012
We propose a special class of functions for mathematical modeling of periodic signals of a special type with a nonuniform distribution of the arguments.

Eclipse Depth Variations in Seven Eclipsing Binaries as Observed by KELT and TESS

The Astronomical Journal
A set of eclipsing binary systems exhibit a changing inclination over time due to the gravitational influence of a third stellar companion. These changing inclinations manifest in photometric observations over time as eclipse depth variations.

KEPLER ECLIPSING BINARY STARS. III. CLASSIFICATION OF KEPLER ECLIPSING BINARY LIGHT CURVES WITH LOCALLY LINEAR EMBEDDING [PDF]

, 2012
We present an automated classification of 2165 Kepler eclipsing binary (EB) light curves that accompanied the second Kepler data release. The light curves are classified using locally linear embedding, a general nonlinear dimensionality reduction tool ...

Modelling of W UMa-type variable stars

South African Journal of Science, 2009
W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.
