Times of minima for a number of neglected eclipsing binaries are presented. Cone search capability for table J/other/IBVS/5502/table1 (Observed stars)

The following Table 1 lists 550 timings of minima of eclipsing binaries secured both by photoelectrical as well as by visual means by BBSAG observers, primarily obtained between...

This research presents new elements for 80 eclipsing binaries found with the help of the ASAS-3 (Cat. ), Hipparcos (Cat. ) and NSVS (2004AJ....127.2436W) databases. Cone search...

A set of 442 eclipsing binaries was selected from the GCVS catalog (Kholopov et al., 2003) that had declination <0{deg}, minimum magnitude brighter than 13.0, and no...

All observations were conducted in Tashkent, Uzbekistan from an urban yard under moderate light pollution. 28cm Schmidt-Cassegrain, 2640mm focal length. German equatorial mount....

In this 55th compilation of BAV results, photoelectric observations obtained in the years 2005 till 2006 are presented on 816 variable stars giving 1722 minima and maxima. All...

In this 68th compilation of BAV results, photoelectric observations obtained in the year 2010 are presented on 436 variable stars giving 784 minima on eclipsing binaries and...

In this 69th compilation of BAV results, photoelectric observations obtained in the year 2010 and 2011 are presented on 503 variable stars giving 767 minima on eclipsing...

The spectra of HT Virginis were collected at 0.5m Newtonian telescope (PST1) equipped with echelle spectrograph (R=40 000). The focal length of the telescope is 2.25m. The data...

I identify the profusion of emission lines seen in IUE spectra of 32 Cyg (K4-5 Ib+B6-7 IV-V) during total eclipse. With the exception of a very few weak lines, all of these are...

VBLUW photometric observations of 13 eclipsing binary stars carried out by C.J. van Houten with the Walraven 5-color photometer between 1965 and 1978 are presented together with...

I present BVRI photometry of short-period (P<1d) eclipsing RS CVn binary star systems collected between 1988 and 2009 at Mount Laguna Observatory. Most of the data are for ER...

This paper continues the publication of times of minima for eclipsing binary stars from observations reported to the AAVSO Eclipsing Binary section. Times of minima from...

In this study we aim to reveal the starspot behaviour in the contact binary PP Lac, using the clues from the eclipse timing variation (ETV) nature of the system, obtained from...

We present the analysis of photometric and spectroscopic variation, and orbital period study of the late-type contact binary system V1191 Cyg. The system is found to be a...

In this study, we present long term photometric variations of the close binary system GO Cyg. Modelling of the system shows that the primary is filling Roche lobe and the...

New photometry for the eclipsing binary BE Cephei was performed from 2008 to 2011.

We present multicolor photometry of the massive interacting close binary system V729 Cyg. The light variations of V729 Cyg were observed in the Bessel U, B, V, R and I bands...

We present a photometric study of a weak-contact binary V873 Per. New observations in BVR filter bands showed asymmetric light curves to be a negative type of the O'Connell...

LU Lac is a neglected W UMa binary star in photometric investigations. In this paper, we present BVRI CCD photometric light curves obtained on one night in 2012. The first...
