Modelling of W UMa-type variable stars
South African Journal of Science, 2010 W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.

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 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].

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

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 314-330, February 2023., 2023 By the selection of the hydrogel composition, applied solvents, and concentration of the cross‐linking compound, it is possible to modify the properties of the materials designated for bioinks for 3D printing in Bone Tissue Engineering. Abstract Alginate‐gelatin hydrogels are the most commonly used materials for 3D bioprinting.
