We present near-infrared JHK_S_ light curves for the double-lined eclipsing binary system Two Micron All Sky Survey J05352184-0546085, in which both components have been shown...

In this paper, we present a complete reanalysis of the eclipsing systems, CM Dra, composed of two dM4.5 stars. New and existing light curves as well as a radial velocity curve...

We present the first direct distance determination to a detached eclipsing binary in M33, which was found by the DIRECT Project. Located in the OB 66 association at coordinates...

We have obtained high-dispersion spectroscopy and BV photometry of two F-type eclipsing binaries, HD71636 and V1022Cas, plus the A-type system OTAnd. Transiting Exoplanet Survey...

In this paper, we present Transiting Exoplanet Survey Satellite (TESS) photometry and high-resolution spectra of the short-period Algol-EW-Boo. We obtained double-lined radial...

The photometric and spectroscopic investigations of ten contact binaries were presented for the first time. It is discovered that the mass ratios of all the ten targets are...

We report long-term UBVRIRcIc photometry of the highly eccentric 12.04 day detached eclipsing binary V490Sct (V=13.1, B9.5+A0,e=0.40), which we use to determine its relative and...

We presented new photometry for four short-period late-type binaries, observed by three small telescopes in China from 2020 September to 2021 December. Seven sets of light...

We observed the post-common-envelope eclipsing binary with a white dwarf component, QS Vir, using the 1.88 m telescope of Kotammia Observatory in Egypt. The new observations...

The primary Kepler Mission provided nearly continuous monitoring of ~200000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary...

As part of our study of the old (~2.5Gyr) open cluster NGC 6819 in the Kepler field, we present photometric (Kepler and ground-based BVR_C_I_C_) and spectroscopic observations...

We present multi-color photometric observations for two neglected near-contact binaries, IZ Mon (P=0.77980^d^) and AR Dra (P=0.67584^d^). By the aid of the updated W-D analysis...

Time-series photometry of the CoRoT field SRc02 was obtained by the Berlin Exoplanet Search Telescope II (BEST II) in 2009. The main aim was to conduct a ground-based follow-up...

The Kepler mission has provided unprecedented, nearly continuous photometric data of ~200000 objects in the ~105deg^2^ field of view (FOV) from the beginning of science...

By analyzing R_c_ and I_c_light curves of the short-period solar-type eclipsing binary GSC 1537-1557 we discovered that it is a shallow contact binary with a degree of contact...

We present a comprehensive re-analysis of stellar photometric variability in the field of the open cluster M37 following the application of a new photometry and de-trending...

New CCD observations for 13 eccentric eclipsing binaries from the Large Magellanic Cloud were carried out using the Danish 1.54 m telescope located at the La Silla Observatory...

Many short-period binary stars have distant orbiting companions that have played a role in driving the binary components into close separation. Indirect detection of a tertiary...

We report extensive high-resolution spectroscopic observations and V-band differential photometry of the slightly eccentric 7.02day detached eclipsing binary V501 Mon (A6m+F0),...

Multiband CCD photometric observations of SZ Her were obtained between 2008 February and May. The light curve was completely covered and indicated a significant temperature...
