New eclipsing binaries with mercury–manganese stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 ABSTRACT Eclipsing binary stars are rare and extremely valuable astrophysical laboratories that make possible precise determination of fundamental stellar parameters. Investigation of early-type chemically peculiar stars in eclipsing binaries provides important information for understanding the origin and evolutionary context of their ...

Galaxies, 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]
Journal 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
The 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

The Eclipses of the Close Binary Star BE UMa [PDF]
International Astronomical Union Colloquium, 1996 BE UMa is a close binary star, not transferring mass, with an extremely hot primary star irradiating the inner face of the cool secondary star. The light curve shows a large-amplitude, sinusoidal variation with a period of 2.29 d, and an eclipse that is centered on the minimum of the variation [1], [3].

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.

A Search for Exoplanets in Short-Period Binary Star Systems [PDF]
Journal of Astronomy and Space Sciences, 2012 This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

Candidate Eclipsing Binary Systems with a δ Scuti Star in Northern TESS Field [PDF]
Research in Astronomy and Astrophysics, 2022 The existence of pulsating stars in eclipsing binaries has been known for decades. These types of objects are extremely valuable systems for astronomical studies as they exhibit both eclipse and pulsation variations.

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.
