An Adaptive Optics Survey of Stellar Variability at the Galactic Center [PDF]

, 2018
We present a $\approx 11.5$ year adaptive optics (AO) study of stellar variability and search for eclipsing binaries in the central $\sim 0.4$ pc ($\sim 10''$) of the Milky Way nuclear star cluster.

STATISTICAL RESTORATION OF SECONDARY MINIMA DEPTHS FOR ECLIPSING VARIABLE STARS AND SPECIFICATION OF THEIR EVOLUTIONARY TYPES

Odessa Astronomical Publications, 2017
30 unknown magnitudes of secondary minima depths for eclipsing variable stars are restored by ZET - method. Evolutionary types of some eclipsing variable stars arespecified on the basis of obtained data.

Eclipsing Binaries in Open Clusters [PDF]

, 2006
Detached eclipsing binaries are very useful objects for calibrating theoretical stellar models and checking their predictions. Detached eclipsing binaries in open clusters are particularly important because of the additional constraints on their age and ...

Parameterization of long-period eclipsing binaries

Open Astronomy, 2022
One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components.

Mass-Accreting Pulsating Components of Algols

Galaxies, 2022
We present a review of the latest results of studies of the class of mass-accreting pulsating components of semi-detached eclipsing binaries known as oEA stars.

Fundamental Properties of Late-Type Stars in Eclipsing Binaries

Galaxies, 2022
Evidence from the analysis of eclipsing binary systems revealed that late-type stars are larger and cooler than predicted by models, and that this is probably caused by stellar magnetic activity.

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 ...

The binary properties of the pulsating subdwarf B eclipsing binary PG 1336-018 (NY Virginis) [PDF]

, 2007
Aims. We present an unbiased orbit solution and mass determination of the components of the eclipsing binary PG1336−018 as a critical test for the formation scenarios of subdwarf B stars. Methods. We obtained high-resolution time series VLT/UVES spectra
