  • Velocities of WOCS 24009 and WOCS 40007 in NGC 6819

    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...
  • Kepler Mission. VII. Eclipsing binaries in DR3

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

    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...
  • Times of minima for 21 early-type SMC eccentric EBs

    We present the apsidal motion and light-curve analyses of 21 eccentric eclipsing binaries located in the Small Magellanic Cloud. Most of these systems have never been studied...
  • Multicolor eclipse data for 6 new binaries

    We present the discovery and characterization of six new M dwarf eclipsing binary systems. The 12 stars in these eclipsing systems have masses spanning 0.38-0.59M_{sun} and...
  • Variability of low-mass stars in SDSS Stripe 82

    We present a catalog of periodic stellar variability in the "Stripe 82" region of the Sloan Digital Sky Survey. After aggregating and re-calibrating catalog-level data from the...
  • Orbital circularization of Kepler eclipsing bin.

    The rate of tidal circularization is predicted to be faster for relatively cool stars with convective outer layers, compared to hotter stars with radiative outer layers....
  • Compilation of W UMa stars

    We present a statistical study of the largest bibliographic compilation of stellar and orbital parameters of W UMa stars derived by light-curve synthesis with Roche models. The...
  • uvby photometry of AB Cas

    Table 1 contents 1313 simultaneous measurements collected in each of the four uvby colours of the Stromgren photometric system for the semi-detached Algol-type eclipsing binary...
  • Kinematics of W UMa-type binaries

    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...
  • Differential photometry of the EB* HATS551-027

    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},...
  • HIDES. II. Double- and triple-lined objects

    We present the results of our spectroscopic observations of eight detached eclipsing binaries (DEBs), selected from the Kepler Eclipsing Binary Catalog. Radial velocities (RVs)...
  • Parameters of 15 Cataclysmic Variables

    We present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the relationship...
  • TYC 3700-1384-1, V1511 Her, V1179 Her minima

    The first multi-colour light curve models and period studies for the totally eclipsing W UMa stars TYC 3700-1384-1, V1511 Her and V1179 Her are presented. All three stars are...
  • V839 Cep UBVRIRcIc light curves

    New high-precision photometric measurements of the eclipsing star V839 Cep (P=9.96-day, V(A+B)=9.64mag, e=0.07, B6 V + B7 V), which is the A component of the visual double star...
  • V361 Cam UBVRRcIIc light curves

    Our multicolour photometric measurements of V361 Cam (P=8.64day, V=10.79mag, e=0.12, B5 V + B9 V) over the past 16 years, as well as TESS data, allowed us to determine for the...
  • Semi-detached eclipsing binaries

    The catalog contains two parts: 96 well known semidetached eclipsing binaries with known photometric and spectroscopic orbits (table1.dat), and 136 semidetached eclipsing...
  • Catalog of eclipsing binaries parameters

    This catalogue contains information about 44 binaries with known photometric orbit elements and unknown spectroscopic one. Cone search capability for table V/118/catalog (Catalog)
  • Catalogue of field contact binary stars

    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...
  • Catalog of early-type contact binaries

    For the first time the early type contact systems were identified as an individual class in M.A. Svechnikov's Catalogue [1] in 1969, which contains 8 systems of this type. The...
