Long-period binary systems containing a B-type hot subdwarf (sdB) and a main-sequence (MS) companion are thought to originate from binary interactions involving stable mass...

Hot subdwarf binaries provide stringent constraints on envelope stripping and binary mass transfer. However, robust identification of these systems in large spectroscopic...

The Galactic Be star binary MWC 656 was long considered the only known Be star +black hole (BH) system, making it a critical benchmark for models of massive binary evolution and...

Red giants are increasingly used as stellar population tracers due to their well-understood evolution and the availability of asteroseismic observables. However, stellar...

The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. We aim to understand the...

NGC 2506 is a rich, intermediate-age (2.0Gyr), metal-poor ([Fe/H]~-0.2) open cluster. This work presents the results of 12,157 spectroscopic radial-velocity measurements of 2442...

This catalog is abstracted from the Card Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...

The complete description of the catalogue, as well as the notes, is to be found in the Publ. Dominion Astrophys. Obs. 17 (1989). The present machine-readable version was...

We have created specialized target lists for radial velocity surveys that are biased toward stars that (1) possess planets and (2) are easiest to observe with current detection...

The Ninth Catalogue of Spectroscopic Binary Orbits continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators...

Observations with the correlation radial velocity meter of ADS 9731 were carried out during 1996-1997. We established that the components A and D of the visual quadruple system...

It is found from the observations with the correlation radial velocity meter that the primary component of the visual double star ADS 9167 is a single-lined spectroscopic binary...

Based on the correlation radial-velocity measurement, we discovered new spectroscopic subsystems in the components of six visual multiple stars and determined the elements of...

The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will obtain space-based uninterrupted light curves for a large sample of bright white dwarfs distributed across...

We report 1212 radial-velocity (RV) measurements obtained in the years 2009-2013 using an iodine cell for the spectroscopic binary {nu} Octantis (K1 III/IV). This system...

In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the Spectrographe pour l'Observation des PHenomenes...

We present multi-epoch spectroscopic observations of the massive binary system WR21a, which include the 2011 January periastron passage. Our spectra reveal multiple SB2 lines...

Radial-velocity observations spanning more than a century are used to produce a reliable orbit of the {delta} Sagittae system. We find an orbital period of 3703.7+/-1.5 d and a...

We present long-term high-resolution spectroscopic observations of the very active RS Canum Venaticorum-type star V711 Tau, obtained during several observing runs from 1998 to...

We present analysis of precision radial velocities (RV) of 1134 mostly red giant stars in the southern sky, selected as candidate astrometric grid objects for the Space...
