  • Radial velocities of solar-type stars

    We studied for duplicity the 167 F7-G8 IV or V primaries within 25pc of the Sun according to their Hipparcos parallaxes and between declinations of -30{deg} and +75{deg}. Cone...
  • MK classifications of spectroscopic binaries

    New MK spectral classifications are given for 145 spectroscopic binaries (SBs) with A-F primaries because two-dimensional types are lacking for more than one-third of the A-F...
  • Velocities of Cygnus OB2 massive binaries

    We analyze orbital solutions for 48 massive multiple-star systems in the Cygnus OB2 association, 23 of which are newly presented here, to find that the observed distribution of...
  • 5yr radial velocity measurements of 19 Cepheids

    We investigate the radial velocity (RV) variability and spectroscopic binarity of 19 Galactic long-period (P_puls_>~10d) classical Cepheid variable stars whose trigonometric...
  • Short period spec. & EBs (LPSEB) from LAMOST & PTF

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

    We developed a convolutional neural network model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single-exposure medium-resolution spectra...
  • Double-line spectroscopic binaries from LAMOST

    Double-line spectroscopic binaries (SB2s) are a vital class of spectroscopic binaries for studying star formation and evolution. Searching for SB2s has been a hot topic in...
  • New SB1s with sp. orbits from LAMOST DR8 LRS

    The LAMOST Low-Resolution Spectroscopic (LAMOST-LRS) Survey provides radial velocities of 10 million stars. These observations can be used to identify new single-lined...
  • MC WC/WO stars - Colliding winds

    Files br22rv.dat, br31rv.dat, br32rv.dat, ab8rv.dat, wr9rv.dat and wr30arv.dat contain spectroscopic radial velocity data of six Magellanic Cloud WC/WO class binary Wolf-Rayet...
  • Chromospherically active binaries

    The kinematics of 237 chromospherically active binaries (CABs) were studied. The sample is heterogeneous with different orbits and physically different components from F to M...
  • Orbits of 30 spectroscopic binaries

    Three of the six southern Clube Areas that were mainly observed at the European Southern Observatory and whose principal results are given in Paper XVI (Griffin & Cornell...
  • W UMa type and CAB stars dynamical evolution

    Orbital angular momentum (OAM, Jo), systemic mass (M) and orbital period (P) distributions of chromospherically active binaries (CAB) and W Ursae Majoris (W UMa) systems were...
  • Spectroscopy around lam Ori and sig Ori

    We have obtained multi-epoch, high-resolution spectroscopy of 218 candidate low-mass stars and brown dwarfs (BDs) in the young clusters around {lambda} Ori and {sigma} Ori. We...
  • RV catalogue of O-type stars in NGC 6231

    We present the results of a long-term high-resolution spectroscopy campaign on the O-type stars in NGC 6231. We revise the spectral classification and multiplicity of these...
  • Orbits of {beta} Ret and {nu} Oct

    New astrometric-spectroscopic orbital solutions for the single-line K-giant binaries beta Reticuli (P~5.2yr, e=0.3346+/-0.0004) and nu Octantis (P~2.9yr, e=0.2358+/-0.0003) have...
  • UBVRI differential photometry of DM UMa

    We present extensive UBVRI photometry of the active RS CVn binary DM UMa obtained at two different observatories over 1988-2008.
  • RV catalogue of O-type stars in NGC 6611

    Based on a set of over 100 medium- to high-resolution optical spectra collected from 2003 to 2009, we investigate the properties of the O-type star population in NGC 6611 in the...
  • RV catalog of O-type stars in IC 2944 and Cen OB2

    Using an extended set of multi-epoch high resolution high signal-to-noise ratio optical spectra, we re-address the multiplicity properties of the O-type stars in IC 2944 and in...
  • Radial velocity monitoring of PG 1018-047

    About 50 per cent of all known hot subdwarf B stars (sdBs) reside in close (short-period) binaries, for which common-envelope ejection is the most likely formation mechanism....
  • SDSS-UKIDSS white dwarf-main sequence binaries

    We develop optical and near-infrared colour-selection criteria based on the model colours of binaries consisting of a white dwarf and a main-sequence star. Using our...
