On the Crimea-Texas project "Surface abundances of light elements for a large sample of early B-type stars".

open access: yesOdessa Astronomical Publications, 2017
A significant part of the project is already implemented. Actually, high-resolution spectra of more than 100 early B stars were obtained. A number of basic parameters was determined including the effective temperatures Teff , surface gravities log g ...

Photometric Investigation of WY Leo: An Eclipsing Binary System with $\delta$ Scuti Component

open access: yesJournal of Advanced Research in Natural and Applied Sciences
Eclipsing binary stars with $\delta$ components are exceptional systems for gaining a deeper understanding of stellar systems. WY Leo is one such system exhibiting $\delta$-type oscillations. However, it has not been extensively studied in the literature.
