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... -
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... -
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... -
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... -
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... -
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... -
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... -
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... -
Radial velocities of DG Leo
DG Leo is a spectroscopic triple system composed of three stars of late-A spectral type, one of which was suggested to be a delta Scuti star. Seven nights of observations at... -
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... -
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... -
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... -
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... -
Galactic O-type stars from LAMOST spectra
This paper reports 209 O-type stars found with LAMOST. All 135 new O-type stars discovered so far with LAMOST are given. Among them, 94 stars are first presented in this sample.... -
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,... -
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... -
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... -
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... -
Ultraviolet Spectral Atlas of VV Cephei
The first observations of the ultraviolet spectrum of the binary system VV Cep (M2Iab + B?) during total eclipse have been made with the HST. A rich emission-line spectrum is... -
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...
