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

Automatic classification of eclipsing binary stars using deep learning methods [PDF]

open access: yesAstronomy and Computing, 2021
In the last couple of decades, tremendous progress has been achieved in developing robotic telescopes and, as a result, sky surveys (both terrestrial and space) have become the source of a substantial amount of new observational data.

New Pulsating Stars Detected in EA-type Eclipsing-binary Systems Based on TESS Data [PDF]

open access: yesAstrophysical 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 ...

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.

Eclipsing Systems with Pulsating Components (Types β Cep, δ Sct, γ Dor or Red Giant) in the Era of High-Accuracy Space Data

open access: yesGalaxies, 2021
Eclipsing systems are essential objects for understanding the properties of stars and stellar systems. Eclipsing systems with pulsating components are furthermore advantageous because they provide accurate constraints on the component properties, as well

The BINSYN Program Package [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
The BINSYN program package, recently expanded to calculate synthetic spectra of cataclysmic variables, is being further extended to include synthetic photometry of ordinary binary stars in addition to binary stars with optically thick accretion disks ...

A New Catalog of Am-type Chemically Peculiar Stars Based on LAMOST

open access: yesThe Astrophysical Journal Supplement Series, 2023
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 Data Releases 8 (v1.0), 9 (v0), and 10 (v0), which greatly expands the database
