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

open access: green, 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.

Fundamental Properties of Late-Type Stars in Eclipsing Binaries

open access: yesGalaxies, 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.

MASS TRANSFER IN ECLIPSING BINARY STARS

open access: yesOdessa Astronomical Publications, 2017
Analysis of the properties of the eclipsing binary stars shows, that the stream-like mechanism of the mass transfer switches on at a contact evolutionary stage, preceding to a stage of binaries with a subgiant.

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

open access: yesAstrophysical 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 ...

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

open access: yesAstronomy & 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

Classification of OGLE Eclipsing Binary Stars Based on Their Morphology Type with Locally Linear Embedding [PDF]

open access: yes, 2021
The Optical Gravitational Lensing Experiment (OGLE) continuously monitors hundreds of thousands of eclipsing binaries in the Galactic bulge field and the Magellanic Clouds.

A Distance Determination to the Small Magellanic Cloud with an Accuracy of Better than Two Percent Based on Late-type Eclipsing Binary Stars [PDF]

open access: yesAstrophysical Journal, 2020
We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important galaxy.

Fundamental effective temperature measurements for eclipsing binary stars – I. Development of the method and application to AI Phoenicis [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
Stars with accurate and precise effective temperature (Teff) measurements are needed to test stellar atmosphere models and calibrate empirical methods to determine Teff.
