This research paper presents a comprehensive analysis of RR Lep and BF Vel, two southern short-period semi-detached oscillating Algols (oEA stars), which are shown to be triple...

Eclipsing binaries are crucial for understanding stellar physics, allowing detailed studies of stellar masses, radii, and orbital dynamics. Recent space missions like the...

Massive stars play a crucial role in the cosmic dynamics and chemical evolution of galaxies. Despite their significance, our understanding of their evolution and properties...

The study of apsidal motion in eccentric eclipsing binaries provides an important observational test of theoretical models of stellar structure and evolution. New ground-based...

Tidal deformation breaks the axisymmetric structure of stars, and this may affect stellar activity. This effect has been demonstrated in theoretical analyses and simulations,...

This catalog is abstracted from the Card Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...

The catalogue of 361 galactic contact binaries is presented. Enlisted contact binaries are divided into five groups according to the type and quality of the available...

We present the results of the reduction of our photometric and spectroscopic observations for the eclipsing binary SZ Cam performed with the telescopes at the Astronomical...

The results of a UBVR photometry observations and light curve analysis are presented for eclipsing binary, BZ Mon.

The results of a UBVR photometry observations are presented for eclipsing variable EQ Ori. The binary was observed 1988 with the 1-m telescope at Maidanak Observatory (Uzbekistan).

New photoelectric UBVRI observations of the eclipsing variable V1016 Ori have been obtained with the AZT-11 telescope at Crimean Astrophysical Observatory and with the Zeiss-600...

New uvby-{beta} photometry of the unique binary RY Sct is reported. The results were interpreted using the light-curve synthesis method.

The results of a UBVR photometry observations are presented for eclipsing binaries KV Cyg, V435 Cyg and V699 Cyg. Each binary was observed 1989/91 with the 60 cm telescopes at...

The results of a UBVR photometry observations are presented for eclipsing binary V1481 Cyg in the open cluster NGC 7128. The binary was observed between 1993 and 1995 with the...

Photoelectric UBVR photometry of 2 eclipsing variables are presented. Each binary was observed between 1989 and 1995 with the 60 cm telescopes at the Maidanak Observatory...

Photometric analysis and spectroscopic study of the long-period low-mass-ratio deep-contact binary KN Per were performed. The light curves of the BV(RI)c band were from the...

New CCD photometric observations of UZ Leo were obtained between 2012 February and 2013 April, and on 2017 February. Its physical properties were derived from detailed analyses...

RU Eri is a near-contact eclipsing binary (V~9.24mag) with a 0.632-day orbital period. The Wilson-Devinney program is used to simultaneously solve new UBV light curves obtained...

We present a spectrum and a photometric analysis of the newly discovered, high-amplitude, solar-type, eclipsing binary HO Piscium. A spectroscopic identification, a period...

YY Cet is a 10.5 mag semidetached variable with a 19 hr orbital period. The Wilson-Devinney program is used to simultaneously solve two new sets of UBV light curves together...
