CCD differential photometry in the Stromgren u, Johnson V and Cousins I bands is presented of three hot, luminous eclipsing binary stars in the Magellanic Clouds. Observations...

The catalogue lists 167 eclipsing binary stars in the Small Magellanic Cloud detected in the database of time-series photometry for 400000 SMC stars acquired by the Microlensing...

We present the first estimates of the relative and absolute parameters of the eclipsing binary EQ Boo based on a light-curve analysis (P=5.43d, V=8.8m). This star is...

We have obtained the first UBVR photoelectric light curves for a recently discovered eclipsing binary with a period of 9.33d and an appreciable eccentricity (e=0.08). We have...

We use estimates of ages and abundances made for a set of eclipsing binaries (Kovaleva, 2001, Cat. <J/AZh/78/1104), to re-calculate observational values of radii, effective...

Based on the set of high accuracy observational data on the components of SB2 eclipsing binaries and the grid of stellar models calculated by Geneva group for the wide range of...

I have performed V photometric observations of the well known eclipsing elliptic variable AS Cam which demonstrates slow apsidal motion for a long time. All available light...

With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released. Deriving parameters for...

Starting from more than 11200 short-period (less than 0.5 days) EW-type eclipsing binary candidates with the All-Sky Automated Survey for Supernovae V-band light curves, we use...

A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope...

Based on 2 minute cadence TESS data from sectors 1-50, we report the results of the systematic extraction of {delta} Scuti-type pulsations in the 6431 eclipsing binaries with...

Contact binary star systems represent the long-lived penultimate phase of binary evolution. Population statistics of their physical parameters inform an understanding of binary...

The O'Connell effect --the presence of unequal maxima in eclipsing binaries-- remains an unsolved riddle in the study of close binary systems. The Kepler space telescope...

We present a catalog of 97 uniformly vetted candidates for quadruple star systems. The candidates were identified in TESS full-frame image data from sectors 1-42 through a...

Pulsating stars in eclipsing binaries are very important for understanding the structure of stellar interiors through asteroseismology because their absolute parameters such as...

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...

During the primary Kepler mission, between 2009 and 2013, about 150,000 preselected targets were observed with a 29.42 minute long cadence. However, a survey of background stars...

The Optical Gravitational Lensing Experiment (OGLE) continuously monitors hundreds of thousands of eclipsing binaries in the Galactic bulge field and the Magellanic Clouds....

We present a statistical study of the largest bibliographic compilation of stellar and orbital parameters of W UMa stars derived by light-curve synthesis with Roche models. The...

Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information,...
