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...

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...

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

There is an ongoing debate on whether hot Jupiter hosts are more likely to be found in wide binaries with separations of ~100AU. In this paper, we search for comoving, very wide...

The realistic simulation of variable star populations is fundamental to determine the selection function and contamination in existing and upcoming multi-epoch surveys. We...

In this work, we have studied the variable stars in the young open cluster NGC 1893 based on a multiyear photometric survey covering a sky area around the cluster up to...

We have identified and photometrically characterized a sample of 230 detached close-orbiting eclipsing binaries with low-mass main-sequence components (LMMS) from the Catalina...

We report the detection of 3714 variable stars towards the Galactic bulge, including 2521 previously uncatalogued variables, using time-series photometry extracted from data...

We present the results of our spectroscopic observations of eight detached eclipsing binaries (DEBs), selected from the Kepler Eclipsing Binary Catalog. Radial velocities (RVs)...

We present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. Thirteen of these eclipsing systems are newly discovered. For all 47...

We construct a sample of 9380 contact binaries (W UMa systems) by using the Catalina Real-Time Transient Survey Variables Sources Catalogue. By measuring brightness change...

We report the discovery and characterization of a new M-dwarf binary, with component masses and radii of M_1_=0.244_-0.003_^+0.003^M_{sun}, R_1=0.261_-0.009_^+0.006^R_{sun},...

We report eclipse timing variation analyses of 26 compact hierarchical triple stars comprised of an eccentric eclipsing ("inner") binary and a relatively close tertiary...

We report the discovery of the transiting exoplanets WASP-69b, WASP-70Ab and WASP-84b, each of which orbits a bright star (V~10). WASP-69b is a bloated Saturn-mass planet...

HD 181068 is the brighter of the two known triply eclipsing hierarchical triple stars in the Kepler field. It has been continuously observed for more than 2yr with the Kepler...

The kinematics of 129 W Ursae Majoris type binaries (W UMas) were studied. The sample is heterogeneous with different orbits and physically different components from F to K...

Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information,...

We present the physical parameters of 2335 late-type contact binary (CB) systems extracted from the Catalina Sky Survey (CSS). Our sample was selected from the CSS Data Release...

We present a catalog of 1143 periodic variables, compiled from our image-subtracted photometric analysis of the K2 Campaign-0 super stamp. This super stamp is centered on the...

The parameter distribution of binaries is a fundamental knowledge of the stellar systems. A statistical study on the binary stars is carried out based on the LAMOST spectral and...
