The masses of stars and planets can be measured dynamically in binary systems. For an unresolved binary, time series astrometry yields some orbital parameters, but it cannot...

Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of...

Understanding the survival and orbital evolution of brown dwarf (BD) companions during the post-main-sequence (MS) evolution of their host stars is increasingly important,...

In preparation for the release of the astrometric orbits of Gaia, Shahaf et al. (2019MNRAS.487.5610S) proposed a triage technique to identify astrometric binaries with compact...

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Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...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...

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...

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...

This paper presents an extensive overview of known and proposed RR Lyrae stars in binaries. The aim is to revise and extend the list with new Galactic field systems. We utilized...

The two dominant features in the distribution of orbital parameters for close-in exoplanets are the prevalence of circular orbits for very short periods, and the observation...

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...

The abundances of chemical elements in the atmospheres of seven classical barium stars are derived. Cone search capability for table J/AZh/82/231/stars (Star positions and...

Heartbeat stars (HBSs) are astrophysical laboratories for studying binaries with eccentric orbits. A catalog of 173 Kepler HBSs was reported by Kirk+ (2016, J/AJ/151/68), and we...

We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in...

A comprehensive catalog of 623 galactic eclipsing binary (EB) systems with eccentric orbits is presented with more than 2830 times of minima determined from the archived...

The statistics of the angle {Phi} between orbital angular momenta in hierarchical triple systems with known inner visual or astrometric orbits are studied. A correlation between...

The Doppler technique measures the reflex radial motion of a star induced by the presence of companions and is the most successful method to detect exoplanets. If several...

APOGEE spectra offer <=1km/s precision in the measurement of stellar radial velocities. This holds even when multiple stars are captured in the same spectrum, as happens most...

We present spectroscopy and orbital periods Porb for 30 apparently nonmagnetic cataclysmic binaries with periods below ~3hr, nearly all of which are dwarf novae, mostly of the...

The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope (SOAR) in 2018 are given, totaling 3097 measurements of 2427 resolved...
