  • Galactic LMXBs catalog

    Low-mass X-ray binaries (LMXBs) are high-energy sources that require multi-wavelength follow-up campaigns to be fully characterised. New transients associated with LMXBs are...
  • SB9 orbits with HERMES/Mercator RVs

    The Gaia mission is delivering a large number of astrometric orbits for binary stars. By combining these with spectroscopic orbits for systems with two observable spectra (SB2),...
  • Exoplanets parameters

    The number of discovered exoplanets now exceeds 5500, allowing statistical analyses of planetary systems. Multi-planet systems are mini-laboratories of planet formation and...
  • Eclipsing binary parameters

    Eclipsing binary systems provide the opportunity to measure fundamental parameters of their component stars in a stellar-model independent way. This makes them ideal candidates...
  • New binary systems in Magellanic Clouds

    Period change studies offer a novel way to probe the evolution and dynamics of Cepheids. While evolutionary period changes have been well studied both observationally and...
  • Dormant 33 solar-masses black hole

    We announce the serendipitous discovery of a nearby (590pc) binary system composed of an old very metal-poor giant star orbiting a black hole with an estimated mass of...
  • Detached eclipsing binaries lifetime of starspots

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

    Classical Cepheids provide valuable insights into the evolution of stellar multiplicity among intermediate-mass stars. Here, we present a systematic investigation of...
  • TESS OBAF-type eclipsing binaries

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

    Hot sub-luminous stars represent a population of stripped and evolved red giants located at the Extreme Horizontal Branch (EHB). Since they exhibit a wide range of variability...
  • Bulk metallicity of giant planets around M stars

    Determination of the bulk metallicity of giant exoplanets is essential in order to constrain their formation and evolution pathways and to compare them to the Solar System....
  • Newborn Be star system

    Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been...
  • RVs of binaries black hole/Sun-like stars

    Stellar-mass black holes descend from high-mass stars, most of which had stellar binary companions. However, the number of those binary systems that survive the binary evolution...
  • COU 247, ADS 3672 & ADS 15182 observations

    This paper presents new orbits for two visual double stars COU 247 (CCDM 00095+1907) and ADS 3672 (STT 95, CCDM 05055+1948) and a revised orbit for ADS 15182 (A 772, CCDM...
  • Double stars measurements

    624 Micrometer Measurements of 224 pairs with a 32.5 cm Cassegrain, 719 Measurements of 310 double stars with a 360 mm Newtonian are given. Cone search capability for table...
  • 9 visual double stars orbital elements

    Orbital elements and ephemerides for 9 visual double stars are given. Cone search capability for table J/A+AS/132/253/table (General parameters)
  • Double star measurements 1995-1997

    We present speckle observations of 48 double and multiple stars observed with the 2-meter ``Telescope Bernard Lyot'' (TBL) in December 1995, January 1997 and June 1997. Angular...
  • Catalog of binary UV Ceti stars

    A catalogue of nearby UV Ceti type flare stars in (137) visual binary systems is presented in the form of two separate tables of information. The catalogue has developed from...
  • Orbit and mass for 22 visual binaries

    This paper presents orbits and masses for 22 visual double stars, partly derived using their last observations made with the speckle camera PISCO. For 13 of them we have...
  • MACHO Variables V.

    We report the characteristics of 611 eclipsing binary stars in the Large Magellanic Cloud found by using the MACHO Project photometry database. The sample is magnitude limited,...
